TreyHarris can somebody with a working pugs svn checkout help me out with something? should only take a minute or two.... 00:17
markstos feather needs a little help from audrey or an admin. Running pugs there returns: "user error (Incompatible version number for compilation unit
Consider removing /usr/local/lib/perl6/Prelude.pm.yml and make it again"
00:17 plisk__ joined
markstos TreyHarris: I'll try {}. 00:17
TreyHarris markstos: yes, gaal was looking for sudo to fix it himself, but he didn't find it
markstos: what OS are you building under?
markstos I'm on feather, (Linux), but also have an older pugs on FreeBSD, which doesn't have Parrot or Perl5 support. 00:18
TreyHarris oh
well, if feather's pugs doesn't work, and that's what you're using, i think we're not going to get anywhere :-)
markstos "looking for sudo" ? I assume you mean looking for some kind of access rights, not looking for the binary, which is /usr/bin/sudo 00:19
TreyHarris looking for sudoers access
markstos pugs works on feather, it's just a warning that slows things down a wee bit and is annoying. 00:20
TreyHarris yeah, without parrot or perl 5, your BSD won't help me either, as there's a couple regexps in the script i wanted you to try
ah, ok, in that case, try running util/test_loh_segfault.pl 00:21
(i committed it in r12932)
markstos It just printed out some instructions...
TreyHarris follow them :-) 00:22
markstos segfault.
TreyHarris email me the yaml please when you're done? 00:23
markstos TreyHarris: sent, from my feather account. 00:26
It said "success: y", where I guess success is defined as segfaulting...
?eval my @a = ( { a => 1}, { b => 2 } ); say @a.perl; 00:28
00:28 evalbot_12929 is now known as evalbot_12934
evalbot_12934 user error (Incompatible version number for compilation unit Consider removing blib6/lib/Prelude.pm.yml and make it again ) OUTPUT[[{("a" => 1),}, {("b" => 2),}] ] Bool::True 00:28
markstos TreyHarris: I think it's something about the interactive pugs, since it is segfault-free, otherwise. 00:29
00:29 azr|elious is now known as azr|el
TreyHarris markstos: thank you :-) 00:30
yes, "success in duplicating the segfaulting issue" :-)
interesting, in your yaml, were the last three ? items (pugs_revision, success, uname) all indented farther to the right than the other items? 00:31
00:31 aufrank joined
aufrank hi hi 00:32
markstos TreyHarris: probably not. It was probably pasting into vim that did that.
TreyHarris ah, ok
thanks
markstos TreyHarris: This fails too: pugs -e 'say ({a => 1}, {b => 2}).perl'
By failure, I mean "fails to reproduce the segfault issue"
success: f 00:33
TreyHarris yeah, i spent some hours looking for some way to reproduce it non-interactively, since obviously that is a very non-optimal way to test
hmm. i suppose i could probe for Expect, and use that....
TreyHarris hrms
markstos TreyHarris: But if it's reproducible on feather, it will be easy for audrey and and a number of others to work with it. 00:35
TreyHarris guess so. since gaal couldn't reproduce it, i thought maybe gathering info on OS, GHC, etc. might be helpful 00:40
markstos In Perl 5, I could say "$meth->$name". Even after re-reviewing S12, I'm having trouble finding something that works like $meth.$name in Perl6. hints ? 00:53
TreyHarris um... i'm confused. $meth is a reference to a method, and $name is... what? 00:55
markstos A method name. 00:56
But it's determined at run time, so it I can't just be $meth.something_concrete.
TreyHarris huh, i've never seen that before. so you'd have "sub foo... my $f = \&foo; my $foo = "foo" ... $f->$foo"? and what would that do? 00:57
wolverian markstos, do you mean $obj->$meth?
markstos Yes!
Sorry.
wolverian hm. I don't know. any tests for it? 00:58
TreyHarris oh. IIRC, that was one of the first questions you asked when you arrived on #perl6. :-) maybe you didn't understand the answer then?
markstos Or I have a short memory 00:59
Trey who?
;)
Please freshen my buffer.
TreyHarris ?eval class Point { has $.x is rw; has $.y is rw; method dist { sqrt($.x**2 + $.y**2) } }; my $meth = &Point::dist; my Point $p .= new(x => 2, y => 3); say $meth($p:); 01:03
evalbot_12934 user error (Incompatible version number for compilation unit Consider removing blib6/lib/Prelude.pm.yml and make it again ) OUTPUT[3.605551275463989 ] Bool::True
TreyHarris make sense?
wolverian I'm not sure why $p.$meth wouldn't work
(but it doesn't)
TreyHarris $meth($p:) 01:04
wolverian yes, I am not blind, thanks. :-)
I am just wondering about the other syntax.
TreyHarris wolverian: sorry, i was giving that as markstos's answer, not correcting you. 01:05
wolverian oh, sorry, then.
aufrank does $p: $meth; work?
markstos TreyHarris: Thanks. testing now.
TreyHarris $p.$meth doesn't work because $meth could potentially be anything, maybe a reference to a sub or a method even outside of $p's class 01:06
wolverian aufrank, that makes no sense, I think.
TreyHarris so we have to call it as a subroutine, not as a method
using the colon to force $p to be taken as invocant
markstos TreyHarris: Yes, I recognize the use of the colon for that purpose now. 01:07
My own test isn't working, though. I'm reviewing what I might be doing differently now.
I figured it out. "$p" has to be a coderef, not just a scalar as can be the case in Perl5. 01:08
aufrank wolverian: no sense why?
TreyHarris markstos: $p a codref? no, $p must be an object, and $meth must be a routineref 01:09
or rather, $meth must be Routine, and $p must be consistent with $meth's invocant's type
markstos TreyHarris: Sorry, I was using Perl5 spec. That's what I meant.
s/spec/speak/ 01:10
TreyHarris and you swapped your varnames again ;-)
back in a few &
markstos We all have our strengthnesses and weaks. 01:11
wolverian weaknesses 01:13
er
yeah, mine is being blind to irony. 01:14
markstos :)
Here's what I was looking for. By using a symbolic reference, the $meth can be a scalar, rather than a Routine. 01:19
?eval class Foo; method foo () { say "found!"; } my $obj = Foo.new; my $rm = 'foo'; &::($rm)($obj:);
evalbot_12934 user error (Incompatible version number for compilation unit Consider removing blib6/lib/Prelude.pm.yml and make it again ) OUTPUT[found! ] Bool::True
01:23 kanru joined
aufrank markstos: why's it so important that you use $meth = 'foo' and not $meth = { say "found!" } ? 01:26
(curious, not dubious)
markstos This is the dispatch system of CGI::Application. Ther defines the strings that correspond to the possible methods that can be dispatched. 01:27
s/Ther/The user/ 01:28
aufrank I see
markstos To turn the strings into code references beforehand would be more work.
aufrank I know you've been looking at the given/when construct... could users define possible method names there, along with blocks? 01:29
markstos But this is a prefect use of symbolic references in Perl6, so I'm happy.
I haven't tried,
and I'm not familiar enough the spec to say for certain.
aufrank given $input { when <foo> { say "found!" }; when bar { say "want a pint?" } }
s/bar/<bar>/ 01:30
markstos so you are suggesting using given/when as a dispatch system for this case ? 01:31
aufrank just wondering if it would work 01:32
markstos It might. I'm happy with the symbolic ref solution for now. I don't see any drawbacks to it.
aufrank yeah, I think the way that the given/when dispatch would fit in would be complementary to your approach, not replace it 01:33
markstos Ah.
aufrank if you had certain method names that you wanted to provide defaults for, you could dispatch to those specifically, and then your fallthrough could be the symbolic ref approach 01:34
markstos But there is one default, called AUTOLOAD, and I've already handled that case.
I used the !! ?? construct to handle that part. 01:35
aufrank makes sense
just for completeness sake, this is what I'm thinking of (I think). given $input { when <known_argument> { say "this one is built in" }; default { &::($_)($input:);} ; } 01:37
markstos I see. 01:38
aufrank just wanted to work through it for my own sake ;)
markstos If I call routine(self:), it should still find "routine" even if it's in a parent class, since 'self' is the invocant, right ? 01:50
I think it should, so I'll write a test. :) 01:53
Ok. I committed a new failing test. From a grep, it seemed there weren't other tests for the interaction between symbolic refs and OO. 02:03
svnbot6 r12935 | markstos++ | Commit test: &::($meth)(self:) should find method in parent class

I have to ask: did you actually have jifty stuff _localizing_ to false values? 02:59
audreyt lunch, bbiab :) 03:04
yes, 0 localizes to 0, and one thing I localize to ''
to hide it from display
obra hah 03:08
but 0->0 should have worked with the existing setup
I appreciate the patch though
(schwern and I had debated it before I implemented, so Iwas amused)

thanks for your help btw
audreyt no prob -- thanks for your report
peacock i'll drop by tomorrow night and let you know how it came out 05:04
audreyt okie. I did duplicate the failure mode and have a working pugs here
so unless our setup differ in subtle ways, it should work for you also

gaal audreyt: [try]?followedBy has its args in the reverse order, as far as my intuition goes. why? is a curried version used somewhere? 05:55
that is, for golf this looks natural: followedBy whiteSpace $ blah
ah, I see it's used infix in one place. mind if I switch it over? 05:56
.oO( it's also against the order of other combinators like sepBy, so maybe not? )
 05:57
audreyt sure, switch it over 06:02
gaal I think sepBy etc. changed my mind :)
did you see my Q about Dog ::T $fido? 06:03
how is that expressed in Param?
currently we have a [Type] member, but nothing else that looks pertinent

gaal audreyt: is it reasonable to rewrite ruleParam like this, or should I schlep ruleFormalParam and convert the result? 07:21
this is a general question about Parser remoosing, I guess
in the long run reqriting is called for, no doubt
07:22 axxsa left
gaal I read "force regen as part of make" as "rm the stale compiled version" :-) 07:22
question is if we want to make "the latest compunit version" something more robust than 07:24
perl -nle 'print $1 if /^compUnitVersion = (\d+)/' src/Pugs/AST/Internals.hs
BTW, lexical question about haskell: in one of my cleanups, I wanted to write: 07:25
let p = MkParam
{ ...
}
but that wouldn't compile! ghc thought I was ending the do-block with something that wasn't an expression
I had to rewrite that as 07:26
let p = MkParam {
...
}
Why?
Is this a layout bug? :) 07:27
ayrnieu that does seem odd, I thought the { } were for overriding the normal indentation style. Well, did you try the latter with } as in K&R ?
gaal ayrnieu: in this case it's for record fields spec. 07:28
k&r doens't really work in haskell :)
audreyt let p = MkParam
q = 1 07:29
vs
let p = MkParam
{ ... }
the layout rule can't distinguish between them
so it requires continuation lines to at least be idented 1spc more
let p = MkParam
{...}
xerox let p =
mkParam { ...
Maybe this buys you something.
gaal aw, that's subtle.
audreyt tries pugs vs strawberry 2 07:32

ayrnieu bought a Zaurus 3200, yesterday :-)
audreyt oooh 07:34
I'd like one too, but my electronics toys budget just disappeared
gaal wonders how soon those things will be able to handle ghc
audreyt I know hugs runs on zaurus 07:35
GHC probably runs also, I think
there's ARM-Linux port
gaal 64mb ram?... probably walks. slowly
xerox I think they were having some kind of weird problems with GHC on ARM
audreyt GHC runs on nokia 770
but there's weird floating point off-by-ones I think
xerox That's a fun device!
xerox played with shapr's one hehe 07:36

gaal audreyt: my pugs has almost 40mb virt, i suppose it might run on such a platform... 07:37

oy, 'use' from interactive pugs is pretty ugly
audreyt it is
technically correct but ugly 07:39
improve the Pretty instance?
gaal what is 'sub {Syn "block" ...' ?
how did the sub come about there?
I think it's better to leave the Pretty as it is, and catch it in the interactive elk. 07:40
audreyt oops, I though you were talking about 07:42
pugs> pugs> use perl5:Test
macro {Prim ([Pugs.AST.Internals.Val] -> () Pugs.AST.Internals.Val)}
the Syn "block" thing shouldn't go back here.

audreyt instance Typeable1 (EvalT (ContT Val (ReaderT Env SIO))) where typeOf1 _ = typeOf ()
which is, of course, entirely bogus, but works fine... 07:45
xerox 's heart explodes
audreyt SIO btw is a union of other three monads 07:46
xerox That's nice :)
What do you use that instance for?
audreyt actually I think it's a pretty clever hack and generally useful
it lets you mix pure, STM, and IO actions
and enter/leave "runlevels"
which will reject unsafe-in-that-level actions at runtime
data SIO a = MkSTM !(STM a) | MkIO !(IO a) | MkSIO !a 07:47
the six-layer monad is pugs's main Eval monad
all runtime happens under there
and since pugs supports thunks
(in the haskell sense)
(Eval Val) is a first class value that must be typeable 07:48
xerox Ah.
You want full power.
audreyt yes.
as spj puts it
"adding in feature to GHC is like throwing raw flesh to hyenas" 07:49
xerox haha 07:50
I am so excited about the Hackaton.
I hope sometime it'll be possible to -Ofun ghc ``easily'' ! 07:51
audreyt you going there?
xerox Nope :( 07:52
audreyt oy :/
xerox Yarrr! :(
audreyt so your Cabal hacks made into GHc 6.6?
including cabal-install?
xerox I think it will not.
Hrmpf.
audreyt oh, we have another year or so to work around the subtle bugs of a pre-alpha design?
j/k :) 07:53
xerox hehe
audreyt JaffaCake's chglog indicates cabal-install is in
xerox Well, it isn't tested enough to be released anyway
audreyt hence my question
xerox Really?
I asked him but I didn't know if he did it
audreyt let me check...
xerox I thought I was going to push them as soon as I got darcs access, which I haven't yet
That's a good thing 07:54
xerox checks something too 07:55

xerox :(
Where do you read that?
audreyt both in the 0901 win32 bindist 08:04
xerox Ah. 08:05
It will not work on win32 now.
It depends on a tar binary :/
I am now doing cabal-put 08:06
audreyt k
uhm
xerox But I can roll up a all-haskell implementation of tar
audreyt ghc can very easily ship tar binary
xerox That works for the purposes of cabal-install
audreyt it does for ar.exe and so on
xerox can it? hm!
Then we could ship cabal-install I think
xerox hacks up cabal-put faster so people try it on monk adding their packages
nothingmuch oosem 08:07
xerox In fact people could have used it before, but nobody seem to have looked at cabal-devel mails
Sigh.

xerox Strawberry is a nice name. 09:27
Eeck!
audreyt which doesn't quite work with GHC's idea of the world
but recently they implemented MinGW compatibility
so we can now work with ActivePerl
but it requires quite a bit of kluges
strawberry/vanilla is community maintained, entirely MinGW based distro
xerox I wonder what do you do in pugsese for mif :: m Bool -> m () -> m () :D
audreyt and uses exactly the same set of tools as GHC
xerox Nice to know! 09:28

xerox ?type unless
lambdabot forall (m :: * -> *). (Monad m) => Bool -> m () -> m ()
xerox Those take Bool, not m Bool :(
audreyt well, if spj fixes the layout rule 09:29
so that you can write
if foo then do
...
else do
...
then mif doesn't win much, no?
xerox It's just to avoid
do ok <- amb

markstos So, I just want to copy an array from a hash key to a plain array. I was surprised this doesn't work: 12:35

ayrnieu ?eval my %h = (a => @('c','d')); my @a = @{%h<a>}; say @a.perl 12:37
evalbot_12940 Error: unexpected "(" expecting "::"
ayrnieu shrugs.
markstos This works, with an extra steps that seem unnecessary: 12:38
?eval my %h = ( a => @( 'c', 'd' ),); my $aref = %h<a>; my @b = @$aref ; say @b.perl;
evalbot_12940 OUTPUT[["c", "d"] ] Bool::True
ayrnieu my @a = @%h<a>; doesn't work similarly? 12:39

markstos audreyt: Should I submit a test for the segfault above ? 12:42
And thanks for the help!
buubot kack!
audreyt sure, commit a test 12:43
it's expected to fail
but not to segfault, obviously
markstos confirmed to work:
?eval my %h = ( a => @( 'c', 'd' ),); my @c = @( %h<a> ); say @c.perl;
evalbot_12940 OUTPUT[["c", "d"] ] Bool::True
audreyt aye. sigil invariance means that when you append prefix sigils 12:44
it's always binding tighter than postfix method calls
as it's considered part of the "var name expression", so to speak
markstos translation? :)
audreyt $$x.foo always means ($$x).foo not $($x.foo) 12:45
and %h<a> is simply %h.<a>
markstos Ah. Got it.
ayrnieu ?eval my @c = @(@('c','d')); say @c.perl
evalbot_12940 Error: unexpected "(" expecting "::"
audreyt @('c','d') is suspicious too 12:46
lambdabot Unknown command, try @list
audreyt you sure you don't mean ['c', 'd'] or just <c d> ?
@(1,2) I think just means (1,2).
lambdabot Unknown command, try @list
ayrnieu here, I mean [<c d>], but I don't know why markstos used it. 12:47
markstos I started with just <c d>, but that didn't work, so I tried other things. I'll try <c d> again, since that didn't seem to be the problem.
audreyt yeah
bbiab... 12:48
markstos Works:
?eval my %h = ( a => <c d>); my @c = @( %h<a> ); say @c.perl;

13:13 hugues23 joined
markstos solved his own problem with: my @f = @( Foo.new.param( key => <c d>).a ); 13:13
audreyt oof. indeed in that case, the .a accessor should return the list in list context
not pretending that it's a scalar
that is a bug
I wonder if it's tested :)
markstos test coming. :)
audreyt but the @() forcecast will always work
even after this is fixed 13:14
so it's a sound workaround :)
markstos Good.
audreyt there's also spec (But not yet implemented) such that you can write
foo.bar.baz.@
to mean
@( foo.bar.baz )
lambdabot Maybe you meant: . v
markstos audreyt: Is there a recommend place to check for existing tests, or should I just poke around on my own.
audreyt which is further nice sugar
grep some keywords like "array" etc in t/oo/? 13:15
markstos Sigils on the right look strange.
k.
audreyt it's okay to dup tests.
13:15 plisk joined
markstos Good. :) 13:15
audreyt just make sure that it's smartlinked this time if you can :)
(since smartlink is our main weapon to fight test dup)
markstos Aha. Will try. 13:16
audreyt yay
markstos forages for breakfast in $localtime.
audreyt thanks ddrescue for sanity
as otherwise dd will take, oh, 5 days.
markstos dd, the lowlevel copy tool ? 13:17
audreyt yeah
my old macbook died with some bad sectors around its 80g hd
"old macbook" sounds like oxymoron. sigh.
markstos Yikes. 13:18
so ddrescue copies even faster ?
or something?
audreyt so this new one (exactly the same spec!) has 120g and I'm dd'ing the old one over with firewire
yes. it dynallocs blksz
so on bad sector it narrows down
and on good regions it ups the blksz
13:19 penk joined

lambdabot audreyt is in #perl6 and #haskell. I last heard audreyt speak 41 minutes and 2 seconds ago.
Limbic_Region audreyt ping 14:13
audreyt pong 14:14
Limbic_Region so yesterday, gaal tried to convince particle and I to try the latest ghc snapshot
as it was a 6.6 rc
I told him it had been b0rk for some time
but we went ahead and tried it anyway
sure enough, it was b0rk - but in a new way
for one, the headers aren't in the usual place 14:15
no problem, just copy them
next, they removed some libs that pugs depends on as extralibs
hrm - problem as Win32 has binary distro and these extra libs are source only 14:16
solution - use Cabal to install them
that is after creating our own Setup.hs
ok, ready to try and compile Pugs
gets through the first 95 steps no problem
and begins its second pass
and then it bombs out
going to nopaste the error - see if it makes any sense to you
btw - did you get the msg I sent you? 14:17
hrm - going to take me a second to nopaste that as I did a realclean inadvertently 14:19
audreyt I did and I sent it to igloo
GHC's release manager
I'm on win32 now
still using 20060819 build
no problem at all
Limbic_Region oh, I was working with Igloo last night 14:20
audreyt oh. I didn't notice that
hopefully he didn't think my mail as rude then
Limbic_Region as well as eivoukko
audreyt since I just repasted your report :)
Limbic_Region doubtful
they were both very intrigued and happy that I (well, we the pugs team) brought the issues forward 14:21
audreyt cool
Limbic_Region They were pretty sure the nightly build for Win32 was b0rk
audreyt yup
I used 0819 to work on strawberry and vanilla embedding
both now works as of tonight
activeperl still needs special handling 14:22
Limbic_Region ok - starting the build now - should take 10-15 minutes
audreyt in Makefile.PL
but vanilla/strawberry now builds using the same code as other unixes
and as such should remain stable without fiddling
Limbic_Region great
audreyt (I also downlaoded activeperl build 819)
and made sure it still works
Limbic_Region (xdg and team)++
audreyt indeed 14:23
Limbic_Region oh, 819 is out
cool - Module::Build should work out of the box thanks to bart, Intrepid, and myself

Limbic_Region wow 14:25
audreyt according to him, he wants people to buy perlapp based on merit and its nice UI
not because they are forced to or locked in
jand++ # very healthy attitude
Limbic_Region well, I am constantly suprised in this community by technical skill and willingness to give freely of oneself
so anyway - the folks over in #haskell went silent the few times I asked about timeframe of fixing the Win32 binary build issues 14:26
so for now, if we can get it working, we should add or update a win32.readme? 14:27
audreyt "a GHC 6.6 showstopper" or something
no... not really
0819 is known to work
only because 0901 is broken, doesn't mean we need to adapt
6.6 should work out of the box with pugs :)
Limbic_Region right 14:28
except it isn't going to unless we have a few brave souls poking and prodding it
markstos uses whatever is on feather 14:29
Limbic_Region presumably, the current ghc release is only b0rk on Win32 so you shouldn't have an issue markstos
audreyt Limbic_Region: exactly. and the fix should be twofold: rolling in extra-pkg into the final .msi
and add the include path in ghc's buildflags 14:30
markstos I'm just saying: If 6.6 were being used on feather, I would be testing with it by default.
audreyt I have no control on the former; the second one, I can probably help.
Limbic_Region audreyt - I am not yet convinced those are the only issues yet 14:31
but yeah, I think your solution approach is the most sane
Happy 1.15 won't build with GHC 6.5 (0819) or 6.6RC btw 14:32
apparently some array bounds changed internally and lots of old programs broke
Limbic_Region just thought he was doing something wrong again

Limbic_Region yes it does

that looks odd to me
markstos just got basic integration with perl5:HTML::Template working with p6:CGI::Application

markstos: !
Limbic_Region: I need the lines starting at
GHC installation path: $ghc_inst_path\n
which should be near beginning
Limbic_Region audreyt - hrm, it doesn't give the full path so ....
ok, you are on the same line of thought 14:37

audreyt 0819 still works, so it's 0909 specific 14:38

Limbic_Region audreyt - oh, I agree but I am not sure it is a ghc problem or a pugs assumption
as with the location of the header files 14:40
audreyt I got the fix.
Limbic_Region kisses audreyt
audreyt smiles
hmm wait 14:41
you put ghc 6.6rc1 into c:\ghc\

svnbot6 r12943 | audreyt++ | * fix #1 for GHC 6.6-rc1 building on win32: use the same runcompiler for build_exe 14:43
Limbic_Region audreyt - yes
one issue I had last night with 3 different ghc's 14:44
6.4.2, 6.5 (0819) and 6.6rc
audreyt if you put it into that dir, pugs should pickup it
Limbic_Region was that I accidently compiled some binaries from one with the other compiler and ended up spending time tracking down wild gooses
hrm 14:45
should it matter where I install ghc?
audreyt no
Limbic_Region ok so do I have to move where ghc is now to make your fix work? 14:46
audreyt no
let me think thru the implications
if you mkdir gcc-lib
in pugs workdir
and copy ld.exe from c:\ghc\gcc-lib there
Limbic_Region ok
audreyt does it suddenly work?
Limbic_Region this happened to us before remember
my bet is yes
audreyt the offending line is Cabal.Distribution.Simple.GHC
(baseDir, _) = splitFileName compilerDir
in 14:47
darcs.haskell.org/packages/Cabal/Di...ple/GHC.hs
somehow it lost track how it was invoked.
Limbic_Region ooh
audreyt that's a new bug
Limbic_Region yeah, that would be a problem
that's ghc issue
audreyt it's "fixed" by esa vuokko
www.mail-archive.com/cabal-devel@ha...00010.html
lambdabot Title: System.Directory.findExecutable and ghc's ld in Windows, tinyurl.com/kfq5p
audreyt that fix broke our assumption
Limbic_Region ghc should not assume the place it was compiled would have anything remotely to do with where it is installed
audreyt still thinking how to do that portably
Limbic_Region ok 14:48
will test the gcc-lib thingy
audreyt k
nothingmuch mooooooooooooooo 14:49
Limbic_Region looks like that was it
markstos wonders if he hears moose noises
audreyt Limbic_Region: ok. now try this 14:50
put gcc-lib under some other PATH
say c:\perl\bin\gcc-lib
Limbic_Region audreyt - isn't that how darwin awards are handed out
audreyt but _not_ under pugs workdir
Limbic_Region k
audreyt my working hypothesis is that it now uses the win32 native SEarchPath
Limbic_Region oh, so shouldn't I then just be able to add C:\ghc to my path?
audreyt well that too 14:51
actually try c:\ghc to your PATH
and c:\ghc\bin
and see if it magicaklly works
Limbic_Region ok - ghc\bin is already there
audreyt (it might not.)
Limbic_Region need to go for a sec - issues with my daughter
audreyt k
Limbic_Region ok, in order to test this theory, since pugs has finished buildihng 14:52

jdv79 hello Limbic_Region. 15:13
Limbic_Region salutations jdv79 15:14
markstos jdv: Moose? Sounds like a Perl5 issue.
Limbic_Region audreyt - what exactly was your fix anyway as I think it may have worked
markstos jdv: the meta model that moose uses hasn't been implemented in pugs yet.
jdv79 i understand that but nobody is anwering my query elsewhere so it was suggested that i try here as a last resort
Limbic_Region ld.exe still isn't found 15:15
but it is finishing the build anyway
audreyt but that isgoing to be bogus
Limbic_Region I had been ctrl-cing after that line of output
let me nopaste the last run
markstos jdv: You could try posting a code example that explains what you are trying to express.
audreyt as it's using the previous output in third-party/installed/Pugs
Limbic_Region this is with no manual fix to the env
audreyt so we're back to sq1: ld.exe not found
markstos jdv: Are you really using Moose in Perl5 or is this a Perl6 question?
audreyt now if you manually tweak env to include c:\ghc in PATH 15:16
and "nmake fast" again, does it make ld.exe found?
Limbic_Region let me blow away dist and pugs.exe
not tweak env
jdv79 yes, of course - p5, this is not a perl6 question.
Limbic_Region and nmake fast
markstos bbiab 15:17
Limbic_Region wow, nmake fast is really fast in comparison
audreyt well, blow away third-partyinstalled\pugs-6.2.12 too while you are at it. 15:18
yes. please do use it to investigate build problems
save lots and lots of time :)
(and with GHC 6.6, the resulting pugs.exe is actually just 20% slower or so)
it's getting to a point where I'm not sure whether we should still make optimzied build the default.
markstos 6.6 is slower ?
Limbic_Region ok - audreyt, different build error 15:19
jdv79 that's ungood news
audreyt markstos: no, the diff between "make optimized" and "make unotimized" is narrower
markstos Ah.
audreyt 6.6 is generally 2~3x faster than 6.4.
markstos Wahoo!
Limbic_Region runtime that is
markstos I look forward to experiencing that.
audreyt yes. compile time is a bit shorter but not dramatically
markstos Oh. 15:20
audreyt but "make fast" produces better code
so you can maybe "make fast" more often.
(the difference: "make fast" uses GHC's own codegen based on C--, and "make optimized", among other things, forks out to GCC)
markstos when I was building my own pugs, I use "make fast", just because I suspected it would be faster. :)
audreyt (and GCC is really, really slow.)
Limbic_Region audreyt - I am reverting back to my original state 15:21
meaning just before I pinged you
audreyt ok...
markstos Is there potential for Perl6 to ever compile quickly with this implementation?
audreyt surely!
the parser is one of our slowerst parts. 15:22
as it's working on a linked list of UTF32 characters, currently
which is the slowest possible sane representation of source code.
SamB oh, yeah, you can do much better soon enough, I think ;-)
jdv79 isn't p6 going to compile itself, in a manner of speaking?
audreyt SamB: I sure hope so ;)
markstos I just know that it seems uncommon to write a language in Haskell, versus, say C. I'm fairly ignorant about these issues, though.
Limbic_Region heh 15:23
the Haskell folks were interested in why we were interested in 6.6rc
audreyt markstos: yeah. most of pugs's slowness comes from the very, very slow representation of strings
markstos and that's fixable?
SamB markstos: well, most of the people who have created mainstream languages haven't known Haskell... and frankly when they did it Haskell wasn't likely very good anyway...
audreyt whenever we switch a part into the new fast packed strings, that part sees 5x or so speedup.
Limbic_Region it is like people today that think perl is just a scripting language 15:24
markstos Wow.
Limbic_Region they are living in the past
audreyt currently only variable names is switched
Limbic_Region haskell did come from academia
markstos should poke around with Haskell more.
audreyt and type names
15:24 justatheory joined
audreyt and already pugs is 35% faster 15:24
Limbic_Region and it likely wasn't very good at anything other than teaching at first
but it has been around the block for a while
audreyt to switch other parts, we need perhaps to forsake GHC 6.4 compatibility
so gaal and I have been holding a bit
Limbic_Region I am fine with that ;-)
audreyt (actually, I've been holding back gaal a bit :))
SamB Limbic_Region: I don't think it was originally intended for teaching, really...
markstos I'm already a fan of darcs, and Haskell by extension.
Limbic_Region SamB - I don't think that's what it was intended for - I said I think that was all it was likely good at (at first) 15:25
markstos welcomes the GHC 6.6 overlords
SamB I think they wanted to play with it and use it in papers
gaal purrs
audreyt it's good for producing PhDs ;)
Limbic_Region audreyt - ok, back to the expected failure
markstos is wrapping up a new blog post about Perl5 embedding and YAML emitting.
SamB audreyt: you have to admit that it is also fun to play with ;-)
Limbic_Region so, we know that moving gcc-lib to pugs working dir works 15:26
I don't know for certain adding c:\ghc to my path will work
because even though it did last time around, so did everything else
gaal beed kinda out of elk today. what's the feature set we absolutely want for Sig for the coming release?
Limbic_Region so let me try that first
audreyt indeed. but we need to do that
Limbic_Region: yup.
gaal and, audreyt, did you see my 'Dog ::T $fido' <=> Pugs.Val.Code.Param question? 15:27
audreyt gaal: rename siglist.t to signature.t
and that'd be good enough for me :)
Limbic_Region gaal, let's gang up on audreyt and get everyone to move off 6.4.x
Limbic_Region is a believer
gaal Limbic_Region: it works for you now? great 15:28
but not sure about all platforms
mac in particular is said to have problems
"the kind audreyt doesn't have"
markstos pugs doesn't seem to be buildable on FreeBSD now anyway, because parrot doesn't seem to be buildable there.
Limbic_Region gaal - well, I wouldn't want anyone to go through what I am going through under normal conditions - so no
Limbic_Region is mostly teasing
but the perf diff is amazing
SamB is that a general statement of fact, or a is it specific?
audreyt markstos: pugs doesn't dep on parrot
Limbic_Region audreyt - good news 15:29
audreyt gaal: I actually have an ibook g4...
Limbic_Region well, not so good news
it doesn't work
SamB (mac being said to have problems)
audreyt Limbic_Region: ok. it's a good news
Limbic_Region but that is good news
yeah
gaal l~r, once 6.6 is available on all platorms in binaries, for sure
audreyt means we are not insane and not seeing phantoms
markstos audreyt: Yes, I built it without parrot, and it worked fine, until I tried to use some kinds regular expressions or rules...
gaal SamB: hearsay, I don't own one mylsef to tell.
markstos and then it complained it couldn't find parrot.
audreyt markstos: oh. that. we're fixing that tomorrow
Limbic_Region gaal - it is avail on Win32 in binaries but still takes a lot to get it working
audreyt markstos: soon you'll not need parrot for that, either! 15:30
SamB I mean, apparantly it is uses a rather odd ABI on x86...
markstos Nice.
audreyt (as it'd use embedded perl5 to call Pugs::Compiler::Rules)
gaal Limbic_Region: I mean releaseworthy packages, e.g. packages for .deb and .rpm etc.
audreyt (which is why I was fighting dmake...)
markstos Now I like working on feather and having pugs rebuilt frequently for me. :)
I also like playing with svk. I had trouble installing that, too...
Limbic_Region ideas? 15:31
[particle] markstos: have you reported parrot build problems with parrotbug?
s/with/to/
audreyt Limbic_Region: so re gcc-lib. does it only need ld.exe there?
Limbic_Region: i.e. did you copy the whole gcc-lib or juts ld?
gaal oooh siglist.t++!
markstos particle: It seemed to be a known issue. The FreeBSD parrot port is marked as "BROKEN". 15:32
audreyt because if it's just ld.exe, we can workaround.
Limbic_Region whole
audreyt ok. please try part.
15:32 iblechbot joined
Limbic_Region but let me test 15:32
gaal audreyt: some future release should use newval Sigs to parse sub declarations, too...
Limbic_Region holding daughter - b aminute
audreyt gaal: certainly...
...that's why we are doing this :)
I mean, Capture should also be used to parse calls. 15:33
it's a prereqto get newExp rolled in.
gaal yeah. so what about the old ruleFormalParam -- should I rewrite it in newmoose, or convert its result?
Limbic_Region attempting
audreyt gaal: which ever easiest. I think newmoose.
gaal ok! 15:34
audreyt woot!
Limbic_Region audreyt - works 15:35
with just ld.exe that is
audreyt Limbic_Region: ok. so, horrible-hack time for now
and I'll try to fix cabal.
gaal brb w/coffee
Limbic_Region yeah, ghc hacking
go audreyt++
Limbic_Region is starting over btw without make fast 15:36
oh wait
you are going to want me to test your horrible-hack
Limbic_Region waits patiently
oh, and are you going to remove your third-party thingy? 15:37
audreyt fixing. 15:39
fixed. 15:40

r12944 | audreyt++ | instead copy ld.exe back into pugsland!
audreyt aufrank: sorry, very much out of context
role is one kind of type
Limbic_Region ooh, that is a horrible hack
aufrank yeah, audreyt, sorry to ambush you ;)
audreyt not more horrible than the old one
Limbic_Region since that appears to fall within p5 space (from what I can tell), I can work on this myself later 15:43
I think I need to go grocery shopping soonish though
nmake fast now
gaal in ruleFormalParam, a 'canonical form' of params is mentioned. is it a "real" form, or just an internal normalization? 15:44

Limbic_Region audreyt - horrible hack worked
audreyt I wonder if I should send a patch on how Hs has influenced p5, citing Scalar::Defer and friends
Limbic_Region: good. horrible hacks usually are that one

audreyt makeshift lasts longest etc :)
Limbic_Region let me know even

Limbic_Region well - I am looking into a fix now 15:48
real fix that is
though you work the Cabal angle
audreyt k.
gaal if I specify two traits, does a comma separate them? 15:50
$x is ref is moose
15:51 araujo joined
audreyt I don't think so 15:51
($x is ref, is moose)
would parse "is moose" as second param 15:52
araujo hi hi

svnbot6 r12945 | audreyt++ | * Comment out the unused require_helper stuff from Prelude.pm to save space and maybe help malaire++ to build.
audreyt depending on your interest area (FFI, Parsec, STM, Typeclass, etc), there's several tasks laying around... 16:02
SamB huh, Parsec... 16:04
iirc someone needs to implement that for packed strings? 16:05
audreyt xerox setup a repo for linspire's packed string parser
but it's not direct port of parsec
SamB oh, that was linspire's was it? 16:06
audreyt and as such needs some tweaks; johnmeacham revived packrat parsing and that may be nice as well
sjanssen is supposed to do full parsec port on packed strings
...but it may or may not have been fizzled.
SamB the packrat parsing looks quite hard to use...
I started to write an XML parser in it and I was mostly struggling with it rather than with XML...
audreyt in fact, I'm not sure what parts of sjanssen's work was completed... 16:07
since pugs can use every bit of his SoC work, salvaging any part would be useful :)
SamB: it's useful when you need lots of backtracking
from what I recall, XML needs no backtracking at all
and as such using it may be asking for pain 16:08

SamB even so, I was struggling with the interface!
audreyt markstos: you want to pass a \$foo into p5 land for modification? 16:12
markstos Yes. 16:13
HTML::Templat accepts a "scalarref" as a template.
If it already works, that's great, but it's low priority for me if it doesn't. 16:14
audreyt indeed there's no easy way. 16:16
clkao: pugs::guts didn't have a TIESCALAR instance
so other kinds of refs work but not SV 16:17
markstos so it could happen eventually ?
audreyt fixing
markstos I better hurry up and write a test, then! 16:18
clkao audreyt: huh?
16:18 Psyche^ joined
markstos I guess I'll need to know what the syntax would be to pass it from one language to the other ,though. 16:18
audreyt well, \$foo should still work. 16:19
markstos Really? It won't form a P6 Capture instead ?
audreyt clkao: p5func(\$p6val)
it will
gaal audreyt: why? captures are xlated to refs in p5 bridge? ew!
audreyt but P6 Capture in p5 land should overload ${} into an assignable thing 16:20
and overload @{} and overload %{}
gaal ah, a la XML::All
audreyt right.
markstos proceeds with a test.
audreyt clkao: nvm, trying to think about passing a pugscapt via p5embed bridge into a Data::Bind-ish Capture callconv object
clkao audreyt: was talking about that to rgs and nick 16:22
svnbot6 r12946 | gaal++ | * Correct handling of required and optional parameters. These all work:
r12946 | gaal++ | :($x) :($x!) # required positional $x

clkao uhm, not cap
svnbot6 r12946 | gaal++ | :($x! = 42) # correctly raises an error
audreyt clkao: D::B callconv natively? 16:23
cool. I figure I don't have to fly to YAPC::EU because you're there :)
clkao not callconv, just the bidning bit
audreyt k. anything?
clkao audreyt: your flattering skill has degraded 16:24
nick tries to escape from me. rgs ponders
audreyt I'm sleepy, so that's to be expected
gaal hmm. should :($x! = 42) raise a special userfriendly error?
audreyt would be nice.
clkao something like what judy does, munging the potinter and stick a flag in it can be doable
markstos I think I've got a test now. Will nopaste it. 16:25
audreyt markstos: btw, the :lang<yaml> bit in your blog post has disappeared
16:25 ayrnieu_ joined
audreyt oh, and you know you can eval with :lang<perl5> too? 16:25

gaal aiiiii that's dirty
markstos My test? 16:27
gaal now i know why people want 64 bit archs. an extra bit to mangle
markstos I think I typo'ed scalar_ref vs. scalarref.
gaal markstos: no, the pointer parasity
araujo audreyt, Sounds fun :-)
markstos audreyt: Yes, I knew about :lang<perl5>.
Limbic_Region audreyt - I *think* I may have found the problem
gaal hmm, looks like third-party/ is always compiled with optimizations, even in make fast? 16:28
markstos audreyt: Is there a :lang<yaml> replacement ?
Limbic_Region and if I am correct, there is absolutely nothing we can do about it
though it won't affect that many people
araujo audreyt, i have been glancing over the pugs code now , don't you have some Haskell-related TODO list or something?
Limbic_Region is testing hypothesis now
araujo audreyt, probably it is a bit difficult for me, since i don't know perl5 at all.
markstos Oh, it' s not gone from the language, just from my post. :) Fixing.
That's better.
16:30 Psyche^ is now known as Patterner
markstos Blog is fixed now. The blog software had a made a <yaml></yaml> tag pair out of it. :) 16:30
clkao audreyt: but valgrind would you it 16:31
audreyt araujo: oh, you don't have to know anything about perl5 :) 16:32
markstos Any hints on how, given a string, I can use it to call a method that may be in a parent class? This doesn't work: 16:33
&::($meth)(self:);
audreyt (a sec)
self.$meth() is canonical 16:34
araujo audreyt, good then :-)
audreyt but it's not yet parsed. I wonder why. 16:35
markstos I like self.$meth(). I thought I tested it before. Re-testing.
bug, most likely.
audreyt tries to think what was blocking self.$meth()
markstos ;-)
I'll make sure there's a test for it. 16:36
audreyt ah. right. reason is that our Exp was not expressive to distinguish $meth(1:) from 1.$meth. 16:37
sadly, our newExp is still not! 16:38
audreyt ponders whether to introduce a new CCallLate node
or desugar that into 16:39
self.META.can($meth).(self:)
which looks ugly.
markstos In Perl5, $self->$meth() worked. So self.$meth() feels natural and expected. 16:40
audreyt and ineed perl5 has special op for that 16:41
markstos Is there something ugly that I can use now, that works?
audreyt $self->meth is method_named, and ->$meth is method
svnbot6 r12947 | audreyt++ | * introduce CCallDyn node to Pugs.Exp, to stand for the
r12947 | audreyt++ | dynamic method case:

audreyt don't; a fix is coming.
give me a few mins 16:42
markstos And a test. :)
audreyt right :)
markstos pets cat and waits.
audreyt parsec. now to run it... 16:43

gaal how do I peek at the current char in parsec?
audreyt getInput
gaal since this can't work: try $ char '!' >> fail "required parameters cannot have default values"
markstos That failing test is in t/oo/symbolic_refs.t, BTW.
audreyt <- lookAhead anyChar
one of the two.
gaal thanks
audreyt np :) 16:44
gaal: btw, is "make ghci" working for you? 16:45
gaal no :(
audreyt judy errors?
gaal no, it's those linkage errors I never tracked down fully 16:46
audreyt oh. colinux
gaal I think threaded/nonthreaded libs or something
yeah
rrr, why doesn't this work? 16:47
ch <- lookAhead anyChar ; when (ch == '!') $ fail "..."
this is not in an optional rule
ah: we're already at the next char for some reason. hmm. 16:48
svnbot6 r12949 | audreyt++ | * "make ghci" needs Judy*.o for now.
gaal oh, of course. heh. 16:49
audreyt getInput would work. 16:50
gaal yes yes, my cursor had moved. fixed, committing
audreyt oh. I'm starting to use this style
Syn "CCallDyn" [...] 16:51
to denote newExp nodes in oldExp
instead of cramming new hacks on old reused nodes
gaal sure, and since "EE" is already taken. :P
audreyt Syn "CCall" and Syn "CApply" would follow I think
aufrank markstos: you instigated something bigger than you expected! 16:52
gaal ah no! unexpected "=" expecting "::", end of input, "?" or "="
audreyt it's in.
gaal dumb
svnbot6 r12950 | audreyt++ | * Dynamic method calls:

gaal unexpected moose, expecting moose 16:53
wow, fast 16:54
audreyt araujo: ok, back to business :) spec.pugscode.org/ can get you started on the thing we are supposed to implement
lambdabot Title: Official Perl 6 Documentation
audreyt araujo: do you have a working pugs built on your machine? 16:55
araujo: one place to hack is to refactor src/Pugs/Type.hs 16:56
which is the oldest part of Pugs still surviving intact
markstos audreyt: Cool! When will pugs on feather catch up ? (Or should I just rebuild my own? )
audreyt such that it can support multiple inheritance.
it will catch up when evalbot say s it is
?eval 1
16:56 evalbot_12941 is now known as evalbot_12946
evalbot_12946 1 16:56
audreyt it's still 4 revs behind
markstos But that part is automated ?
audreyt yup 16:57
a full rebuild is perhaps 5mins
so have patience :)
markstos Sure.
audreyt araujo: currently we use "Tree ID" to denote inheritance; it should use Data.Graph.Inductive
araujo: you can ignore most things in that file 16:59
and simply change the rawTree (found in the bottom of Pugs.Type)
into a acyclic graph
and then fix all the type errors you encounter :) 17:00
currently our subtyping-based dispatch (also known as MMD) doesn't work well for user-defined types, largely because the multiple inherietance relationship is not reflected in the class tree; so making the tree a Graph will suddenly make several tests pass
which would be a good thing :) 17:01
araujo: another good task is to summarize the paragraphs above and put it as a comment above Pugs.Types.rawTree... 17:02
markstos:
my $test = ' &::($meth)(self:) should find method in parent class';
that is not so 17:03
&foo(self:) does not do a method lookup
markstos Ok. I'll remove the test. I wasn't sure.
audreyt foo(self:) would do that
but &foo(self:) is moral equivalent of perl5
(\&foo)->(...)
markstos Should this work: ::($meth)(self:) ?
audreyt I don't think so either
because ::() itself is not valid, iirc. 17:04
markstos Because there's no sigil on the :: ?
audreyt aye.
markstos Anyway, self.$meth solves it, so I'll remove that other test.
&::($meth)(self:) is rather ugly anyway.
audreyt k.
also you were misuing eval_is 17:06
simply is() would do
to protectagainst error, use
is(try{},)
eval_is takes first arg as string not expr. 17:07
as in
eval_is('code here')
which protects against parsefail
but you'd have to write
eval_is('$obj.$meth',..)
instead.
Limbic_Region audreyt - where is Setup.exe created?
markstos audreyt: thanks for the eval_is tip. 17:08
audreyt Limbic_Region: actually on ghc 6.6 we can simply use cabal-setup.exe
Limbic_Region audreyt - well, the issue is with Setup.exe
audreyt it's determined on line 147 and compiled on line 174
wow
Limbic_Region not that you probably didn't already know that
audreyt actually I didn't.
so it tries to find relative to Setup.exe? 17:09
Limbic_Region um, let me be more clear
audreyt that's uhm, very broken
line 147 and line 174 of Makefile.PL is where you want to look
Limbic_Region when $runsetup-.('build'); is run, that's when gcc-lib is not found
so I ran just that from the command line
and sure enough - gcc-lib not found
despite $ENV
er path being correct
so
I thought it was a mingw/msys problem 17:10
but that was a dead end
audreyt what if instead of Setup.exe you run c:\ghc\bin\cabal-setup.exe ?
same build line, just with different .exe
Limbic_Region tries
markstos ?eval 1
17:10 evalbot_12946 is now known as evalbot_12948
evalbot_12948 1 17:10

Limbic_Region error - gcc-lib\\ld.exe doesn't exist
audreyt ok.
Limbic_Region that is when being run from the pugs build dir
markstos feather question: Why does '/usr/bin/pugs --version' disagree with the evalbot? /usr/bin/pugs is recent, but older.
Limbic_Region assumes it is hardcode the $basedir into the executable or something
*shrug*, I am not sure I can track it down further but will look at lines 147 and 174 17:12
svnbot6 r12952 | gaal++ | * :($x! = 42) now gives a friendly error message
audreyt Limbic_Region: er, no need to... I think I know why 17:13
17:13 Southen_ joined
Limbic_Region line 174 of makefile.PL 17:13
the compile ?
audreyt that was where Setup.hs was produced
err Setup.exe
but that's probably dead end too.
Limbic_Region ok - I assumed some of those other parameters might be worth looking into if it affected the way setup.exe functioned 17:14
but I will defer to your better judgement
btw - my util/build_pugs.pl is now filled with warn statements ;-) 17:15
audreyt oh. please make it less noisy
Limbic_Region that was just tracking down where the problem was

audreyt araujo: as long as it compiles, you can try to "make test" 17:53
if not all was failing, then simply commit it
araujo thanks audreyt , and good night :-) 17:54
audreyt also you can talk about what you're going to commit here in#perl6 also
but remember to add yourself to AUTHROS first. welcome aboard!
audreyt waves &
araujo Ok :-)

avar does the perlvar.pod draft live in the pugs repos? 18:25
markstos avar: find . -name 'perlvar.pod' ... says no. 18:26
gaal I wasn't aware one existed 18:30
avar it's linked from the spec in the topic
anyway there's a typo in it, hence the question:)
gaal well, then: yes it does live in docs/AES/S28draft.pod 18:31

oh it looks like it hasn't been updated in a while? HISTORY says 2005-04-11 18:36
avar maybe I should just leave it?:) 18:37
I just saw in on spec.pugscode.org
Yeah, it looks out of date
gaal svk log shows 2005-11-29
well, a rehaul would be needed eventually.. so please fix away
and if you're in the mood, give it a scan viz. other synopses and update accordingly 18:38

wolverian hrm, could someone do s/builtin's/builtins/ on Perl6/Perl5/Differences.pod? I don't have access to a checkout currently and it's bugging me :) 18:42
svnbot6 r12957 | avar++ | * The 'ig' was missing in 'unambiguous'
wolverian (it's under "Builtin Functions")
gaal fixed 18:43
wolverian thanks! :) 18:44
gaal sure
wolverian oh, on that note, the "references are gone" index link does not work, and should be capitalised probably.
gah. sorry, I should just do a fresh checkout 18:45
gaal too tired to fix tonight :)
wolverian no problem, I'll fix it when I get home

my coworker does ref $hr =~ /HASH/i; a lot
integral /i? they're superstitious? 18:50
wolverian and you probably won't be typing the ~~ explicitly either, but using multiple dispatch or 'when'
avar integral: apperently:) 18:51
18:56 buetow joined 19:01 nwc10 joined
avar woohoo 19:02
nwc10 Sorry if this is either an RTFM type question, or a "try it with pugs" (which I don't have to hand), but: if you take a continuation, where one (or more) of the lexical variables are references to deep data structures, does the continuation have a deep copy of those structures, or just a shallow copy?
gaal nwc10: try p6-l? 19:05
nwc10 OK. SO it's not a trivial question? :-)
gaal nobody for whom it's trivial seems to be around :)
integral afaik it should be shallow
it's closing over the variables, not the stuff in them 19:06
nwc10 Ah good. If conceptually it's "closing" then it's the same action as the existing closure implementation in Perl 5. Bad people have got me thinking about continuations and 6 on 5. I'm not promising that I will do anything more than think about them. 19:07

markstos I keep getting "No compatible subroutine &exists" errors on valid hash syntax. By moving the problematic method to a test script, I can see that the whole method is in fact fine. This indicates a problem somewhere else in the class that's causing this problem indirectly, but I'm sure how to find it. 20:29
s/sure/not sure/ :)
gaal rindolf: I don't think you can override instances on type aliases, you need a newtype 20:32
