aufrank TimToady or audreyt: any thoughts on an adverbial form for C< a => \($x, $y) > ? 00:18
ajs_home aufrank: :a($x,$y) ? 00:20
aufrank I'd like that if it were the case
00:20 mako132 joined
aufrank but I think right now :a($x) is a => $x 00:20
and this change would make it a => \($x) 00:21
maybe that's OK
ajs_home ?eval my $x=1;my $y=2; :a($x,$y);
00:21 evalbot_r14076 is now known as evalbot_r14098
evalbot_r14098 ("a" => (\1, \2)) 00:21
ajs_home Ah, I missed your \ 00:22
?eval my $x=1;my $y=2; :a(\($x,$y))
aufrank yeah, I want a literal-capture adverbial pair
evalbot_r14098 pugs: don't know how to toVV': VRef <Scalar:0xb6be0a8c>
ajs_home freaky. That worked in my (few days old) pugs 00:23
aufrank: None the less, that should be the syntax
aufrank ajs_home: yeah, someone showed that earlier. I agree that's the way to do it given the current adverbial syntax 00:25
I just wondered if there was room to add another entry to the list of adverbial forms
ajs_home I can't see that it would save much if we did. (\(...)) would become something with 2-3 fewer characters... for something that's not likely to be used very often, I don't see the advantage. 00:29
Typically captures that users interact with will be in variables (like match results) anyway.
OF outage kind of sucks... oh well 00:31
v6 seems to choke on captures right now 00:33

wolverian hm, the docs on spec.pugscode.org don't resize liquidly to under some specified width, which is a tad annoying if you want to read them with less wide lines 00:52
wolverian checks the css
the width is specified in pixels, which is a big no-no. 00:53
...as is the font size

audreyt @tell cmarcelo wow, great work! I've applied the "use monad, not maybe" pattern to it so we can drop-in C3 into Pugs (or any other monad) right away. see perlcabal.org/~audreyt/tmp/C3.hs 03:00

gaal fancy typeset Haskell in papers always bunches up operators, like >> turning into ». But it should also unify guards to one vertical line whenever possible. 05:04

lambdabot cmarcelo said 7h 2m 11s ago: hi! still not MO for Hs yet but did a little C3 MRO implementation because I didn't found any on the web. comments/ideas/suggestions welcome :) feather.perl6.nl/~

05:15 BooK_ joined
gaal audreyt: for the day, yes 05:15
audreyt 'k 05:16
gaal am having morning drink + email check + backlog
no buyers for those shower pics eh. need to coach nothingmuch on marketing... 05:17
so, what's the svk incantation to switch to a mirror repo? I'm using a local mirror. 05:19
won't svk mi --relocate give me a "different uuid" error?
05:20 agentzh joined
clkao it works if the one you are switching to one is a mirror of the original one 05:21
gaal which neither of the /topical ones are :-( 05:24
audreyt right. 05:26
we need the new box
and run uuidgen on it
TimToady @messages 05:27
lambdabot audreyt said 21h 41m 2s ago: How does S04:927 work with [undef, undef, 1, 5, undef, 6] ?
audreyt TimToady: I think a list-context undef is a dangerous idea... 05:28
gaal spinozaUuidGen = const 1 -- different repos are but aspects of the same object
audreyt unless of could we want to train people to write [*, *, 1, 5, *, 6]
but that doesn't quite mean "uninitialized" 05:29
TimToady ordinary undef should be 1 long always. Not sure about failures
audreyt A list is of undefined
length only if it contains an undefined generator, which, happily, is
what is returned by the C<undef> function when used in list context.
So any Perl 6 function can say
return undef;
and not care about whether the function is being called in scalar or list
context.
gaal $commute &
TimToady that what when I was trying to make "return undef" mean "fail".
audreyt so perhaps that para needs to be fixed
'k
TimToady *was when
yeah.
agentzh audreyt: i'm exceedingly happy to see the tests under t/closure_traits/ now all turn green. :) 05:30
lambdabot agentzh: You have 1 new message. '/msg lambdabot @messages' to read it.
agentzh audreyt++ audreyt++ audreyt++
TimToady still thinking about s{pattern} expr and variations.
audreyt agentzh: thanks a lot for those tests
agentzh: they are very helpful to ensure I got the implemntation right
which took ~4 tries
the only thing I adjusted was that NEXT is always run even on the final loop 05:31
as long as its naturally "next"ing instead of last'ing out
I think it's saner for it to behave that way
agentzh audreyt: those tests costed me a lot of time in the summer. ;)
audreyt because it has to run before evaluating the condition, and without evaluating the condition we don't know if it's the last run
05:32 agentzh joined
audreyt 07:31 < audreyt> because it has to run before evaluating the condition, and without evaluating the condition we don't know if it's the last run 05:33
agentzh audreyt: i've read the irc log. :) 05:34
but i think an explicit last will bypass NEXT {...}, no?
audreyt that is correct 05:35
you tested for it :)
agentzh yeah. :)
audreyt and PRE/POST seems to be a handy thing to have
agentzh indeed!
i love those trait blocks very much. :)
TimToady blushes.
agentzh TimToady: :) 05:36
TimToady: will return bypass LAST {...}?
and leave?
TimToady I don't think so.
agentzh okay. 05:37
i didn't write tests for those cases.
TimToady FIRST and LAST are really traits on the loop as a whole.
audreyt currently I have it run LEAVE but not LAST
TimToady ENTER/LEAVE on the closure it repeatedly runs
audreyt on the theory that nonloop controls does not trigger loop ones
hmm.
but FIRST won't get run if the condition starts out false, no? 05:38
neither will LAST
TimToady I think it's both or neither 05:39
FIRST, LAST, and NEVER. :) 05:40
actually, doesn't python allow else on a loop? or is that some other language?
audreyt I think neither makes quite a bit more sense
the first element of a null list is undefined 05:41
neither is the last element
TimToady yeah, that way they are aimed at control points that are otherwise relative inaccessible. 05:42
one can always say something before or after the loop to get "both".
audreyt right.
TimToady s/or/and/
audreyt in which case they are not really LEAVE on any particular scope
and so "return" not triggering LAST makes some sense, I hope
TimToady I suppose, in the same sense that a goto into a loop might bypass a FIRST. 05:43
audreyt yup.
TimToady but it seems righter the other way 05:44
because people will use them to enforce invariants.
audreyt hm. then I can arrange so it triggers LAST queue explicitly
after LEAVE queue
TimToady the loop as a whole has to have a dynamic scope anyway
audreyt yes, but it has no place on the stack 05:45
TimToady or you don't have anything to capture the exceptions
audreyt it's something like
FOO while 1;
here there's an invisible yet noncapturable {} around FOO
TimToady well, sure, but whenever you have a thunk somebody's doing things to it. 05:47
audreyt nodnod. as LAST doesn't mix with LEAVE ordering anyway, either hanging it around the invisible thunk of invoke that explicitly turns out to be the same thing
TimToady been thinking a lot about thunks with respect to s {pattern} mumble 05:48
and how we can have a way forward on that without confusing people.
the s:g {pattern} syntax is getting stretched out, so I've been looking for a syntactic shim 05:49
so that we don't have to say {...} "..."
which is okay for that case, but confusing to people used to
[] and {} for quotes on the second part.
best candidates I have so far: 05:50
s{foo} -> "bar"
s{foo} = "bar"
s{foo}: "bar"
05:50 agentzh left
TimToady problem with the first is that 05:50
s{foo} -> $foo
is ambig with pointy subs
*blocks
audreyt the colon seems to be the most overloaded one 05:51
TimToady (not really, but visually)
audreyt so overload it poses least problem
;)
TimToady problem with colon is
s{foo}:qq/bar/
suddenly looks like a pair, but isn't.
audreyt an extended comma? 05:52
TimToady the only problem with = is that, as a pseudo assignment, it seems to have the wrong precedence in:
audreyt s{foo} <== "bar"
TimToady $x ~~ s {foo} = "bar"
audreyt but that too is low prec
TimToady yes.
nice thing about : is that we could actually make it a list operator
audreyt yes.
I think the :qq/bar/ part is easily disambig 05:53
TimToady s{foo}: 1..*
audreyt s{foo}: qq/bar/
which I expect people to write that anyway
TimToady oh, another possibility was
s{foo}/"bar" using / for old time's sake
but I just don't like it as well. 05:54
other problem with <== is that it's backwards from the transformative point of view
the = at least finesses that by not looking backwards.
audreyt the / has the same problem as ./method 05:55
TimToady also considered s{foo} => "bar"
nod 05:56
audreyt I like the listop :, because it's not really twisting the meaning
TimToady thing I liked about = is that we already have lots of pseudo assigns that happen at weird times.
though all to declarators at the moment
would be funny if s turned out to be a declarator of substrs... 05:57
audreyt oy...
TimToady but syntactically s{} is a macro, so it can really take anything it jolly well pleases after it. 05:58
audreyt sure, it's just the visualmetaphor 05:59
TimToady also played around a lot with s{foo}.() and friends, but just couldn't make them "think" right.
they don't look at all thunky
considered s{foo}\"foo" too
and \() of course 06:00
other advantage of = is that we could think of it as unary (scalar assign) if we only want it to collect one expression. 06:03
with :, you pretty much are expecting a list, and then you have to 06:04
put parens around the whole thing
(s{foo}: "bar"), more...
vs s{foo} = "bar", more 06:05
which can be visually stopped before the comma
and we can always use = [...] for a changing list.
audreyt s{foo}:{...} will also terminate though, but yeah. 06:06
TimToady not necessarily. 06:07
in .method:{...} it parses as .method: {...}
audreyt it is considered the final element of that list unless followed immediately 06:08
by a comma or comma surrogate.
but yeah.
nothingmuch morning
audreyt hi nothingmuch
TimToady right, so your example can stop there too.
except that it makes no sense to interpolate a closure. 06:09
if the right side is already thunked.
one thing going for bare s{foo} expr is that we could simply outlaw {expr} 06:10
to catch all the P5 mistakes.
doesn't help with [] or () though.
<> will usually work.
unless they try to interpolate 06:11
but I still think it's better to spread it out with : or =
audreyt s{foo}:(...); 06:13
hm. still has to listop problem
TimToady s{foo} = (...) is less problematic that way
audreyt as we can say it's a item=
oh well, I guess = wins on that account then 06:14
TimToady I think it stands out just a hair more too.
without being obtrusive.
audreyt but don't make s{} a declarator :)
it's a macro that parses assignment form, 'sall
TimToady why would I do a silly thing like that.
audreyt :D 06:15
TimToady and I think it compresses better s{foo}=q/bar/
audreyt sometime people is goign to want 06:16
s{foo}.="bar"
I know I've wanted that several times.
TimToady ~= ???
audreyt except it's now ~=
S{foo}.=reverse;
TimToady s{foo}+=42
audreyt yeah. 06:17
s{foo}x=3;
TimToady s{foo}=($/.=reverse)
audreyt could be handy.
TimToady so s{foo} really is a kind of self-hypering lvalue. 06:18
it definitely has some possibilities, though maybe not for 6.0 06:19
audreyt I think it's good jus tto say it looks that way
but saying "$x = s{foo};" is invalid
not all things need to be first class...
TimToady yes, it's really a metaop of some sort.
06:20 marmic joined
TimToady or a term that metas the following infix. 06:20
or sump'n
not sure how this translates to .subst though, unless second arg {$/.=reverse} and such. 06:21
or $() more likely.
audreyt *nod* 06:22
audreyt goes back to relenging -- subsets are now parsed
gaal are nested traits legal? { LEAVE { LEAVE { ... } } } 06:25
newVal allows it
but I'm not sure it makes sense!
audreyt it certainly does
gaal use case?
audreyt you can leave a leave block
LEAVE { UNDO {...} } 06:26
L/L doesn't make a lot of sense but L/U or L/Keep does
gaal okies
only a matter of time till someone writes an interpreter using only closure traits for control
audreyt sure, that's part of perl6's ferocity 06:28
audreyt ponders "a feral language"
gaal Perl's already a creole of sorts 06:29
TimToady booga booga wooga
people *are* going to want to say $obj.=s[foo] = "bar" 06:30
hmm, I wonder if we can distinguish a .subst() normal method from a .subst[] macro, since () always forcing routineness. 06:32
audreyt we certainly can
TimToady assuming subst is defined as a macro, of course, or it'd be .subst.[]
audreyt visually confusing though
mixing quotelikes with methodlikes 06:33
TimToady yeh
I'll leave the method syntax vanilla for now. 06:34
maybe we make a general policy that method macros should be ALLCAPS 06:35
.SUBST[foo] = "bar" definitely stands out...
pretty darn ugly though 06:36
maybe we can come up with something prettier someday 06:37
audreyt oy, [\\] is parsed as \ on infix \ 06:44
if we have a infix \\, how do we explicitly want \\ foled?
folded
[ \\] ?
hm, maybe not 06:45
audreyt chalks that up as "don't do that then"
TimToady < audreyt> oy, [\\] is parsed as \ on infix \ 06:55
that's incorrect. S03 says it prefers the infix.
then [\\\] is the triangular form.
audreyt okie. 06:56
TimToady That's at S03:1036
audreyt &infix:<\\> means actually \ right? 06:57
as <> respects quotes
have to write &infix:{qn'\\'} to get \\
s/quotes/escapes/
TimToady yes
actually, s[foo] x= 3 just turns into .subst(/foo/, { $() x 3 }) since assignment back to $() is already assumed. 06:59
07:00 mac93 joined 07:02 mac93 joined
audreyt [\\] is fixed 07:11
07:13 iblechbot joined 07:15 zakharyas joined
TimToady audreyt++ 07:22
I've checked in the s[foo] = "bar" spec, but we can just deprecate s[foo][bar] for this release. 07:23
actually, almost all the occurrences in pugs were s{foo}{bar}
audreyt so maybe just change them all to say that... 07:24
TimToady to say what?
audreyt I still wonder if quotelike adverbs should simply only take () for args and never other forms. 07:25
to say {}{} not [][]
what I mean is
m:adv(1){...}
but never
m:adv{1=>2}{...}
this is a generalization that can bring back
m:g{...}.
TimToady lemme sleep on it 07:26
audreyt and because m() doesn't match, neither shuld m:g(), and eople will accept that
but m:P5{...} is a compellign use case of not generalizing pair syntax with quotes, and only allow ()
sure :) sleep well
m:!adv will still be sllowed, of course.
allowed, even
07:27 polettix joined
gaal hah! I'm reading a Syn patch and see 07:43

r14119 | audreyt++ | The "callCC" is now used to establish fully reentrant continuations.
r14119 | audreyt++ | The "resetT" guard is only used in coroutines now to limit the

agentzh audreyt is in hacking mode. yay! releng++ 10:44
audreyt SamB: it's actually "svk push" following "svk pull" in my local repo :)
SamB audreyt: ah ;-)
svnbot6 r14120 | audreyt++ | * Pugs.Prim.Eval: Change resetT to tryT.
SamB I was just saying the output was reminiscent of that "darcs pull" sometimes has ;-)
agentzh hmm...i'm wondering why the S29 on the smoke server has craps like "_SMART_LINK_34" :(
SamB its probably supposed to link to something ;-) 10:45
svnbot6 r14121 | audreyt++ | * Pugs.Prim: Restore "yield" and coroutines to their former glory,
r14121 | audreyt++ | by storing a genuine callCC register inside the subCont.
agentzh SamB: right. they're actually placeholders introduced by myself. ;) 10:47
svnbot6 r14122 | audreyt++ | * Pugs.Monad: Establish a resetT boundary upon entering
r14122 | audreyt++ | coroutines, so its "yield" will only capture the control
r14122 | audreyt++ | stack up to that point. However, the &?CALLER_CONTINUATION
r14122 | audreyt++ | there is unaffected.
r14123 | audreyt++ | * Pugs.Eval: Finish excising of resetT and shiftT and replace
r14123 | audreyt++ | them with tryT and retControl.
SamB agentzh: oh really?
agentzh SamB: yes.
SamB note that if I was challanging your statement, I'd hava had a 50% chance of having said "o rly?" 10:48

SamB not sure if that is relevant
svnbot6 r14124 | audreyt++ | * examples/cookbook/01strings/01-02default-variables.pl:

SamB it must be some half-hearted or out-of-date processor
agentzh investigating now...
heh, maybe iblech is using an older version of Pod::Simple::HTML on the smoke server...hehe 10:56

audreyt TimToady: gather/take scopes dynamically right?
sub f { take 3 } # this makes sense, correct?
gather is unspecced in Syn, hence the question 14:50
TimToady the A might have said
audreyt A12 says it's lexical 14:51
I wonder why it's lexical...
I mean, its effect, unlike that of given/when, is dynamic
TimToady ere probably ought to be a dynamically scoped variant.
Unless it should be dynamic by default, in which case there probably
ought to be a lexically scoped variant...
audreyt curiously damian's Perl6::Gather on CPAN is dynamically scoped. 14:52
where is lexical useful, I wonder
TimToady well, the only purpose of a lexical scope would be to prevent people from doing the dynamic version, I guess.
audreyt that's like saying we should have a lexical variant of "next" 14:53
to prevent people using next outside loops...
TimToady go with dynamic then. can always do some kind of stricture later 14:54
audreyt 'k. I'll make it die if not within a gather dyamic scope
TimToady after thinking about s:g() overnight, I think I agree.
audreyt using the same mechanism as next outside loops
hurray 14:55
TimToady gather can be viewed as (potentially) spawning another thread, so given the whole purpose of that other thread may be to generate, it makes sense to have it dynamic. 14:56
must generate some coffee... biab 14:57

fglock audreyt: re ext/Perl6-Container-Array - I found the same error as masak - maybe @array-as-invocant is not parsed correctly? 15:08
audreyt fglock: maybe; or maybe the local push is shadowing the global one 15:11
fglock hmm - circularity problems 15:12
audreyt can you add some trace to see if it's the case?
fglock actually, the error is - No compatible subroutine found: "&items" - looks more like a parser problem 15:13
audreyt no, that means "self" is somehow not a object 15:14
fglock the code reads @.items
audreyt instead it's an Array
fglock k
audreyt @.items is just @(self.items)
lambdabot Unknown command, try @list
masak audreyt: I tried adding a trace using :E in pugs interactive, but I didn't get very far -- seems :E creates a new instance of pugs 15:15
or something 15:16

putter strawman proposals: add two new make targets: "precompiled_test" - tweak config.yml; perl Makefile.PL; make. And "testonly" - only run the test, no make - because make test, which runs make, dumps a great deal of crud at the top of the test log. thoughts? 15:29
audreyt good idea, please commence :) 15:30

TimToady or would that need a bifurcation of the adverb logic?
audreyt sure. can you moose the dynamic gather in as well?
demerphq idly wonders if p6 will have an efficient 'goto' 15:51
TimToady why should it? P5's goto was pessimal by design. :) 15:52
[particle] notes that parrot does
demerphq really?
by design i mean.
TimToady pretty much, though "pessimal" is overstating it.
I didn't want people building efficient switch statements from labels. 15:53
demerphq i was just thinking about state machines and how useful goto is for them
TimToady P5 always scans for the label dynamically, though it does optimize by scanning outward from the current scope.
demerphq but its probably just a sign of oncoming demetia due to too much C programming. :-) 15:54
TimToady it also optimizes by scanning forward from the current location and then from the top to here.
on the assumption that most goto's are forwards.
other than that, it doesn't go out of its way to make it efficient.
demerphq ok.
TimToady because there was always going to be a switch statement someday... 15:55
P5 even had the opcodes for cswitch and nswitch, just nothing ever parsed to them.
demerphq Yes i recall you explaining that one time. 15:56
other question: ive selected (?&NAME) for a recursive call to a named subpattern. Which is different from what Python/PCRE use (partially because we are using the .NET syntax and not the Python/PCRE syntax)
gaal TimToady: duff's device *does* provide a speedup in p5, fwiw.
TimToady P4 actually did have that optimization
demerphq 5.10 will use those ops wont it?
TimToady dunno 15:57
demerphq id have to check, but robin put given into perl 5.9.x sometime back.
rgs nswitch and cswitch aren't used in perl 5. 15:58
the new-style switch in bleadperl is implemented with other ops (given)
TimToady phone...
demerphq ah.
btw, rgs i was just going to C&P my comment about the sytax for the recursive call to a named subpattern. did you see it? 15:59
rgs no.
demerphq c&p'd to p5p 16:00
TimToady sort of a pity you can't use (?<NAME>) 16:01
though maybe (?P6:<NAME>) would work for that.
demerphq thats what we use to declare the buffer.
rgs that you be a bit more symmetrical 16:02
rgs looks at the % key on his keyboard
demerphq declare: (?<NAME>PATTERN) backref: \k<NAME> recurse: (?&NAME)
fglock demerphq: I've got a p6rx-to-p5rx module under way - might be useful for experimenting with p6 requirements
audreyt fglock: as an aside, are you subscribed to p5p?
demerphq fglock: are you targetting perl 5.8 or 5.9.x?
fglock audreyt: not sure, maybe not 16:03
demerphq: 5.8
demerphq ok.
fglock demerphq: but it is not production, so no problem in targetting 5.9

TimToady dunno, it's stock fedora 16:09
audreyt perl -v will show that info
TimToady yeah, P5 should probably avoid (?P
yes, threaded
audreyt because GHC 6.4 -prof+threaded is notoriously broken, so much so that they've taken out that combination in 6.6...

yes, I promised Guido he could have (?P
course, with P6 all bets are off, since there's no (?...) anymore 16:11

ajs_home TimToady <P{...}>
demerphq the question we had a little was whether we should support the Python/PCRE syntax for named buffers as well as the .NET one.
ajs_home I realize the braces are just mean, but there you go ;)
demerphq fglock: what do you mean backtracking into subpatterns is not possible?
fglock actually, I was wondering if we could implement p6-to-rx instead
demerphq: such as /a <ws> \s a/ 16:14
TimToady ajs_home: huh?
demerphq i thought 5.8 supported backtracking into (??{...}) patterns. doesnt it?
fglock demerphq: <ws> is a method
demerphq but if ws is a method that resolves to a pattern... 16:15
ajs_home TimToady: Was just thinking out loud about (?P...) in P6.
demerphq anyway, 5.9.5 does, unequivocally, support backtracking into a subpattern.
ajs_home <P something> perhaps just <P ...>
demerphq: subpatterns ne sub-rx/rule 16:16
demerphq for instance $ws=qr/\s+/; /a (??{$ws}) \s a/x does.
audreyt demerphq: is $ws=qr/\s+/ still much slower than $ws='\s+' ? 16:17
demerphq er, i didnt know it ever was.
fglock demerphq: should I be afraid of the "highly experimental" notice in the docs in 5.8?
demerphq fglock: not really. ive been meaning to ask on p5p if we could tone those notices down. 16:18
they wont be removed.
their behaviour may change subtly however.
most likely for the better. but whatever.

TimToady subpatterns in P6 really are full-fledged subroutine calls. They're not special-cased into the regex engine. 16:22

TimToady fglock: it's a form of backtracking, but doesn't actually let the sub do sub-ish things on the fly, since the sub is just precalculating a regex to hand back. 16:33
svnbot6 r14165 | audreyt++ | * Pugs.hs: pugs -c should not imply -d... 16:34
putter the regexp spike, whose syntax was p5 regexps plus <foo>, just converted the <foo args> into (?{dorule( C ,'foo','args')}), where C was the continuation representing the rest of the regexp. so backtracking worked properly.

audreyt yeah. works for quite a few simple cases too
it's Sage's SoC

demerphq grep lets you quantify an open bracket? weird.
svnbot6 r14175 | audreyt++ | * Pugs.Parser: Parse and recognize the @@ sigil. 18:26
TimToady no
grep assumes you meant \*
likewise for a non-sensical $
demerphq aha. right. good thinking. that does sound unwise. 18:27
TimToady unfortunately, by the time I added {n,m}, Perl had already been out in the while matching {...} literally. 18:28

svnbot6 r14178 | audreyt++ | * DrIFT.XML: Add the missing module statement.
TimToady TreyHarris: good question. we could certainly extend it to other types provided the definitions of "clone" and "rw" are clear.
as it is, "readonly" is a bit hand-wavey.
what does it really mean for a non-value type to be "writable"? 18:59
fglock I see ( Var "&infix:~" ) - does "Var" mean it has to lookup &infix:~ at runtime?
gaal yes
it's App Exp (Maybe Exp) [Exp] 19:00
TreyHarris well, the MOP could snapshot the object and throw an exception at runtime if the repr changes. i suppose then objects would have to have some way of saying an given operation should be considered a read but may change the repr or certain attribs may change without "writing" to the object (e.g., caches) 19:01
fglock about ( Ann ... ) - is it meant to attach a (Pos) node?
gaal that is, apply to an Exp (with an invocant, maybe) [and an Exp list]
TimToady yay, r14172 exceeds the purity of Ivory Soap!!!
it's all very transactional...

rodi Good G-d Almighty, audreyt is on a tear. I'm in awe. audreyt++ 19:07
TreyHarris TimToady: one thing that would help me finish the last 10% is to know how you were thinking that a class would go about defining a value type. I can see ways reading between the lines (er, ^LINES?), but particularly wondered whether you'd be okay with a declarative ("i can ask that class/object if it's a value") rather than a behavioral ("if this object's .WHAT matches that object's .WHAT, then they're the same object/value") approach.
erm... that was kind of muddled
fglock "Maybe Param" means "Param" is optional?
gaal fglock: yes
it's like a pointer in c, it's allowed to be NULL. 19:08
TimToady certainly it should at least look declarative
gaal without the Maybe, Haskell's type system guarantees you can't have NULL there.

TimToady because it has a % sigil

TimToady use %$scalar
fglock so it's a compile-time thing 20:17

Limbic_Region @tell audreyt test 12 of ext/Config-Tiny/t/basic.t is failing though the output is correct. My guess is difference of \n versus \r\n 23:28

putter <+<alpha>> is no longer valid, yes? So the distinction between external and internal negation is gone, yes? <-<alpha>> vs <+<-alpha>> 23:42
is there any form of external negation? ie, you have <foo-bar+hee-qux> , can you negate that in any way other than going through and flipping all the signs?

TimToady <!foo-bar+hee-qux> 23:47

because ! turns it into lookahead
putter with a trainling dot I assume... righ
<+<alpha>> is gone?
TimToady yes
putter ok, will update tests. thanks :) 23:48
