anything ABORTFOO is a fossil from before the xact mechanism existed 04:40
it assumed one could backtrack with a die/eval, which is bogus when continuations are being emulated 04:41
sorear What is std supposed to do?
TimToady compiles CORE.setting currently, mostly
sorear ah
TimToady but any submodules used by STD

diakopter blinks awake 05:00
TimToady I expected 6, and that's what I got 05:03
sorear hmm. gimme5 seems to be miscompiling STD.pm6:5149
TimToady: but the 'for' produces a lazy list, which is not evaluated until after foo returns because it's in a returning place, and by then the contextual is gone
in: «: $<quotepair><key>» out: [':', '$<quotepair><key>'] 05:04
sorear wonders what the correct out is, for viv
TimToady foo is called in sink context, which propagates to the 'for', which makes it eager 05:05
sorear I thought inwards context propagation was history
TimToady the only reason to evaluate anything in sink context is to have a side effect 05:06

sorear what does temp $*CONTEXTUAL mean? anything useful?
sorear thinks it looks confused 07:30
TimToady should be local $::CURPAD = $::CURPAD
sorear a fossil from $* == $GLOBAL:: days perhaps
TimToady temporizing a lexical differs from 'my' in that it defaults to its outer value 07:31
s/lexical/dynamic/
not a fossil
S02:2711 07:33
and theoretically 'let $*foo = 4' copies its final value outward on success, but not on failure 07:34
sorear TimToady: Is it possible to obtain from STD information on what variables are in scope at what points? STD clearly generates the information... 07:35
TimToady well, $*CURPAD implies the visibility of everything in that pad, transitively through any OUTERs 07:37
and $*CURPKG likewise out through PARENTs 07:38
sorear perhaps Actions.pm should grab references to $*CURPAD, then
or perhaps viv should be refactored as action methods instead of an AST walker 07:39

because of the inability to have "does Positional"
maybe jnthn++ can look into that

Method 'WHAT' not found for invocant of class 'ResizablePMCArray'
09:30 am0c left
pmichaud right, I didn't work on getting the arrays in place yet 09:30
moritz_ ah well, still needs some work
pmichaud I was primarily wanting to get match objects as Rakudo objects
arrays are next
moritz_ sure, it's already a good improvement
pmichaud although *really* ResizablePMCArray ought to be mapping to Parcel, at least.
I'm not sure why that's not happening. 09:31
hmmm. 09:32
I could've sworn that at one point I had RPA acting like Parcel.
maybe I had to take that out.
wonder what happens if I put the mapping back in 09:33
moritz_ $ ./perl6 -e '"abc" ~~ /<alpha>*/; say uc $/'
ABC
\o/
pmichaud yes, I specifically checked that. Match is now ~~ Cool 09:34
ah, I see why I was getting the Integer.Bool failure 09:36
hmmm.
looks like mapping RPA to Parcel has some issues. 09:39
okay, I'll work on it some more tomorrow 09:40
moritz_ will try to backport some methods to Match.pm 09:41
pmichaud like... which ones?
moritz_ .caps, .chunks, .perl
pmichaud okay, those are good ones
moritz_ I need the first two for the book :-)
pmichaud I'd probably like to see .caps and .chunks provided in Regex;Match
but if you want to just do them in p6 for rakudo for now, that's fine.
moritz_ you'll be free to backport them to NQP :-)
pmichaud wfm. 09:42
although .caps and .chunks might actually be easier to implement now since Cursor objects have much more information than Match objects
i.e., rather than trying to build them from Match, better might be from Cursor (which has all of the captures in sequence) 09:43
ah, but those are methods on Match, so that's where they need to be 09:44
never mind, then
moritz_ does a match object still has a back reference to cursor?
pmichaud it does :-)
moritz_ well :-)
pmichaud it might also be a good idea to have the BUILD_MATCH method also build .caps while it is at it :) 09:45
moritz_ I don't think .caps is used often enough to warrant the use of extra memory for it
pmichaud it'd only be an additional array 09:46
but yes, for now I'd go with the backport version.
we can improve things a bit later
(and when I see the backported version, I can see about migrating to nqp also) 09:47
Su-Shee what's the official way to install a perl6 module nowadays? I throw it into my PERL6LIB path?

snarkyboojum isBEKaml: try a make realclean; perl Configure.pl --gen-parrot; make?
mberends Su-Shee++ # for motivation
isBEKaml snarkyboojum: done that already. perl Configure.pl --parrot-config to point to my latest parrot build.
parrot was built an hour ago. 11:28
snarkyboojum isBEKaml: I had a build failure this afternoon, and had to do a make real clean
Su-Shee mberends: let me put it that way: if I ignore the entire environment and just throw everything into @*INC and write stupidly DBI and just exchange -> with . it works perfectly fine. (though _seriously_ slow)
snarkyboojum but different error about Stringy or something
isBEKaml: what platform are you building on? 11:29
isBEKaml snarkyboojum: linux x86 32 bit
mberends Su-Shee: very nice. sorry about the slowness :-/
Su-Shee mberends: not your fault :)
snarkyboojum isBEKaml: Mmm.. builds on for me
*ok
Su-Shee blames mysql from now on.
isBEKaml snarkyboojum: lemme try once again. I do make realclean and build. Somehow it failed this time. :( 11:31
snarkyboojum isBEKaml: good luck
isBEKaml: you don't use Configure to get the right parrot for you, but build it separately? 11:33
sorry, Configure.pl
isBEKaml snarkyboojum: I Configure and build parrot first and then use Rakudo's Configure.pl to point to the latest parrot_config 11:34
snarkyboojum oh
I just use Configure.pl with --gen-parrot to get the parrot version in build/PARROT_REVISION and build it, before building rakudo 11:35
that way it's just perl Configure.pl --gen-parrot; make; and I'm done
isBEKaml snarkyboojum: the problem with that is, it checks out everytime nuking it to get the same revision over again from the PARROT_REVISION file instead of just svn upping it. 11:38
snarkyboojum isBEKaml: it shouldn't
unless the version has changed.. ok :) 11:39
isBEKaml snarkyboojum: I'm building rakudo again. hopefully, it should build this time . :) 11:40
snarkyboojum isBEKaml: but using --gen-parrot ensures you're building it against a revision everyone else is building it against at least 11:41
isBEKaml snarkyboojum: I'm bleeding edge! ;)
snarkyboojum isBEKaml: but rakudo may not build on latest parrot (as has happened recently quite a bit) 11:42
isBEKaml: PARROT_REVISION is basically telling you what version of parrot plays nicely with bleeding edge rakudo :) 11:43
isBEKaml snarkyboojum: yeah, but I found the error message to be odd: Class '[ 'GatherIterator' ]' not found 11:44
snarkyboojum: I think, your error message was odd too. Stringy's just a role to String types and there's nothing in it. :)
snarkyboojum well I had a build error to do with masak's buf changes, doing a role stringy

that works
jnthn However, a later error means we never compile and install that meta-op sub.

pmichaud: A composition conflict, perchance?
pmichaud didn't look like one
colomon jnthn: nothing quite that complicated, but there are tests for one or two levels in nesting.t
jnthn OK, you're liable to get one.
pmichaud first stage problem was method "Bool" not found for class Integer
jnthn colomon: I just looked in there, but saw nothing fudged.
pmichaud: Oh, oddness.
pmichaud yes, I know what is causing that 14:02
jnthn pmichaud: But if you're going to do both roles you will get a conflict you need to resolve at some point.
pmichaud: Because role Positional[::T = Mu] { ... method of() { T } }
moritz_ back
jnthn And similar for Associative
pmichaud well, thus far I'm getting errors that aren't at all saying anything about conflicts
jnthn So you want a method of() { Mu }

Su-Shee ok. first I need mozarella caprese. then I touch databases again. 14:31
moritz_ jnthn: how do I iterate over a ResizablePMCArray in rakudo? 14:33
in Perl 6 code :-)
isBEKaml in #perl6, do we have to be explicit? :-)
moritz_: ^^ :P 14:34
moritz_ well, I know how to iterate over a RPA in PIR
and over a Perl 6 array in Perl 6
pmichaud simplest is probably to convert the rpa to a Seq and then iterate over that.
jnthn Aye
moritz_ Seq.new($RPA) ? 14:35
pmichaud should work.
RPAs are basically parcels
(parcels are basically rpas)
jnthn pmichaud: I want to try and get decent backtraces in, and am thinking it may be nice to provide an overridable method in HLL::Compiler 14:36
pmichaud: Then languages can implement it to do their own thing.
pmichaud jnthn: that's what I'd like also :-)
so, +1
jnthn pmichaud: OK. Any ideas what to call it, and where to hang to call for it?
pmichaud I'd even like HLL::Compiler to provide a sane deffault
oh, how about 'display_backtrace' ?
or 'dump_backtrace' 14:37
jnthn That'd work. Do we want a seperate one for when in the repl too?
pmichaud or even 'backtrace'
just do the basic one to begin with, and I'll take a look at it
moritz_ somhow 'for Seq.new($rpa)' only does one iteration, even though $rpa has two items
pmichaud I'll have a better idea then where it should go and when
moritz_: maybe Seq.new($rpa).eager 14:38
moritz_ I'm iterating over indexes now
that's ugly, but it works
\o/ most .caps/.chunks tests pass
only failure: $/.chunks should return a List, returns a GatherIterator 14:39
I'll fudge that one
jnthn pmichaud: The thing is that it seems we might want to put it in eval
pmichaud: But that isn't really want we want either
Since that's what other languages call to eval our code.
pmichaud: Not to mention that interactive expects to call it and get the exception. 14:40
pmichaud jnthn: I don't think it belongs in eval, no
jnthn pmichaud: Below that is only HLLCompiler.command_line and HLLCompiler.main
pmichaud it could go in evalfiles 14:41
and I'm fine if it goes in .main
jnthn pmichaud: But that's not in the call chain if we do perl6 -e "...awful things..."
pmichaud er, .commandline
.commandline would certainly in the call chain, wouldn't it? 14:42
*certainly be
jnthn pmichaud: Yes, that always is.
14:42 hercynium left
jnthn pmichaud: That seems workable. 14:42
pmichaud start with commandline then
jnthn pmichaud: OK. Seems we inherit that one form PCT::HLLCompiler.
Which is...in the Parrot repo?
pmichaud oh, ick.
yes, in the Parrot repo
jnthn Hm
Well, we could put the .backtrace in nqp-rx of course 14:43
Like, check if there is a .backtrace method
If yes, call it
pmichaud start with that
jnthn If no, just re-throw
OK
isBEKaml hey, speaking about backtraces, wouldn't it be nice if we have line numbers or there abouts indicated by the compiler when it barfs?
jnthn isBEKaml: We do for compile time errors, it's the runtime ones we seem to suck at. 14:44

moritz_ what *should* .keys on a match object return?
pmichaud I've been wondering where .keys should go
.keys on Match should probably fail
or it would return @().keys, %().keys
(i.e., the union of all keys)
moritz_ I'd prefer that
jnthn pmichaud: rt.perl.org/rt3/Ticket/Display.html?id=62528 seems to want it to be the same as %().keys 15:05
oh, maybe not
it'd work if it returned the union in that case too
(since there's no positional captures)
pmichaud at any rate, all of the array and hash methods still need a ton of work (not just on Match)
moritz_ aye 15:06
pmichaud I was a little surprised to see that Hash ~~ EnumMap
and postcircumfix:<{ }> on EnumMap is returning a proxy
probably shouldn't be a proxy there
jnthn pmichaud: EnumMap seems to be the new name for Mapping
pmichaud (since it's immutable) 15:07

colomon foreign objects? I feel like I must have missed something cool while I was out herding 2 year olds.... 15:43
pmichaud colomon: foreign objects are those that aren't part of the Rakudo hierarchy
e.g., Parrot objects
colomon pmichaud: sure, but why did you do it now? that's the interesting question... :) 15:44
jnthn pmichaud: In the meantime, see gist.github.com/418336
pmichaud colomon: oh. when I add 'does Positional' to Match, the role composer ends up making a call to &infix:<===> which in turn ends up making a call to &prefix:<?>
which in turn attempt to call .Bool on whatever argument is passed
but at the time that this is taking place, parrot Integers don't have a 'Bool' method yet 15:45
jnthn pmichaud: oh argh, that patch sucks...ignor eit.
pmichaud (that doesn't come until later)
and we have a Parrot integer because it got autoboxed from within &infix:<===>(Integer, Integer) 15:46
so, at that point the Parrot Integer is a "foreign object" that doesn't know how to respond to .Bool, but it does know how to respond to VTABLE_boolean, so we use that.
jnthn: umm.... what patch?
jnthn pmichaud: :-)
pmichaud: The one in the gist
pmichaud oh
I didn't see that :) 15:47
colomon pmichaud: gotcha. interesting and cool.
jnthn pmichaud: For what you've run into, it's that the role composer tries to get the name of a method by doing .name on it
pmichaud: Which fails on Parrot subs.
pmichaud: Going to just stringify it instead, since it stringifies to its name for Perl 6 and Parrot ones. 15:48
pmichaud jnthn: +1
jnthn pmichaud: Hopefully that deals with it.
pmichaud colomon: we do a similar thing for .[] and .{} also -- if the target object doesn't have the appropriate method, then we fall back to parrot's vtable interface
jnthn pmichaud: The awkward thing we may hit is if you want to compose Positional into something and then after that write another multi postcircumfix:<[ ]> in the class. 15:49
pmichaud jnthn: I don't need the postcircumfix:<[ ]> there if "does Positional" works.
Su-Shee mberends: is there a reason for the loop with $i instead of for $native_row -> $bla ... ?
jnthn pmichaud: OK
pmichaud (and "does Positional" works if "does Associative" isn't present... but then other things break) 15:50
mberends Su-Shee: a rather trivial reason: it was the least-change translation of the Perl 5 equivalent test, for easy reference in case it went wrong somewhere. 15:51
Su-Shee mberends: in $native_row[last_element_of_my_row] is something like this: udofoobarfoobardatadata 15:53
what's that?
mberends eek, probably a bug or a NYI bit 15:54
hopefully not an off-by-one error, indexing beyond end of array 15:55
the native array is not as error-friendly as a Rakudo array
Su-Shee it segfaults if I grab an index beyong. 15:56
beyond.
jnthn pmichaud: Gah, well, that only gets us a little further... :-/
Method 'multi' not found for invocant of class 'Sub' 15:57
Well, can workaround that too. 15:58
pmichaud jnthn: yeah, that's what I was starting to see -- a bunch of little pieces that seem to get us one smaller step along.
would it help if Positional was written in p6?
jnthn pmichaud: *very* much so
pmichaud: These kinds of things are why Associative is.
mberends Su-Shee: that may be a(nother) reason to stick to a C-style loop
pmichaud okay
jnthn pmichaud: Here's the thing that got me *really* stuck though. 15:59
pmichaud: It seems we want to ahve the commonalities in Associative and Positional.
pmichaud: e.g. handling slices etc
pmichaud: And then classes implementing the role would supply the way to get just one attribute.
Su-Shee mberends: also it seems that I can't treat a native array the same way as rakudo arrays?
jnthn pmichaud: gah, just one item.
For a single numeric index.
Su-Shee mberends: like de-referencing it?
jnthn pmichaud: Trouble is, the composition will end up failing because you have a Parrot multi and along with it a Perl 6 multi. 16:00
Su-Shee sticks with the c loop.
jnthn pmichaud: And are trying to combine them into one.
pmichaud jnthn: right, I recognize that. :-)
jnthn pmichaud: So may just be best to bite the bullet and move Positional to core.
pmichaud: There's no problem at all with adding a role to a class through augmnet.
pmichaud jnthn: okay. Well, you could try one more workaround, or I could work on moving Positional to core (or some combination of the two) 16:01
I'm inclined to do the latter
jnthn pmichaud: Do the latter
pmichaud okay
jnthn pmichaud: Because otherwise we only get more problems further down the line.
pmichaud adding a role to a class with augment is augment class Foo does Bar { } ?
jnthn pmichaud: Also, by taking Numeric rather than ['Integer'] will fix other problems we have. 16:02
pmichaud: Yes, exactly that. :-)
pmichaud jnthn: okay. I'll work on that.
jnthn OK
pmichaud it'll help prep for list refactors too.
afk for a bit
16:05 tedv| left

moritz_ the really odd thing is: inside a module I get a syntax error for »
but it parses with >>
will try to reproduce...
pmichaud rakudo: my $x = [1, 2, 3]; .say for $x.list 16:27
p6eval rakudo bbb336: OUTPUT«1␤2␤3␤»
pmichaud (ah, jnthn++ already tried that one) 16:28
moritz_ so should it be list($obj).list ? :-) 16:31
pmichaud no 16:33
$obj.list is sufficient
moritz_ ... unless $obj is a foreign object
pmichaud in this case, it just means we have to get .list working 16:34
on Match
moritz_ .list works on Match :-)
pmichaud is it returning a flattening list?
rakudo: 'abc' ~~ /<alpha>+/; .say for $<alpha> 16:35
p6eval rakudo bbb336: OUTPUT«a␤b␤c␤»
moritz_ good question... at least it returns a Perl 6 list
pmichaud that's wrong.
moritz_ oops
wait 16:36
TimToady rakudo: .say for [<a b c>]
p6eval rakudo bbb336: OUTPUT«abc␤»
moritz_ I thought list() was non-flattening, and .list was flattening?
pmichaud list() flattens objects that flatten
$<alpha> isn't a flattening object (because of the $) 16:37
although
perhaps I'm wrong there
since it's really $/{'alpha'}, which *would* flatten
moritz_ rakudo: .say for [<a b c>].list
p6eval rakudo bbb336: OUTPUT«a␤b␤c␤»
moritz_ pmichaud: is that wrong too?
pmichaud that's right 16:38
rakudo: .say for list([<a b c>])
TimToady modulo it's supposed to be .flat, as of Feb
p6eval rakudo bbb336: OUTPUT«abc␤»
pmichaud that's also right.
mberends Su-Shee: to be able to commit, you may have to edit fakedbi/.git/config and change "git://github.com/" to [email@hidden.address]
TimToady shouldn't the stringifier insert spaces
?
pmichaud TimToady: yes, I think it should.
TimToady: I'm not sure what's up with that -- I'm pretty sure that worked at one time 16:39
anyway, .list (really .flat) will convert a non-flattening scalar into a flattening list
Su-Shee mberends: will do.
pmichaud while list(...) creates a list, flattening any of the items inside that are naturally flattening
(i.e., that aren't scalars) 16:40
moritz_ Match.list uses the sub form internally
so that's probably what's wrong
it was the only way I found that would turn a RPA into a Perl 6 list
TimToady so flat([1,2,3]) stays [1,2,3], i.e. non-flat 16:41
pmichaud of course, the issue here is that $<alpha> isn't a Match object to begin with, so Match.list doesn't apply anyway :)
moritz_ I should probably create a new Seq, and setattribute '$!stoarge' it
ah, right 16:42
TimToady re $<foo> vs $/<foo>, I suspect we should make those act like var vs expr
moritz_ rakudo: .say for 'abc' ~~ /(.)(.)(.)/
p6eval rakudo bbb336: OUTPUT«abc␤»
pmichaud TimToady: what about $<foo bar> ?
TimToady which is an argument that the flatten flag is basically syntactically applied
pmichaud (the flatten flag is already syntactically applied for the most part) 16:43
TimToady well, that's an interesting corner case, but I'd argue to treat as a variable for consistency, i think
pmichaud for now I think I'd prefer that $<foo> and $/{'foo'} continue to act the same.
I think that's generally more consistent. 16:44
TimToady mebbe
pmichaud (I can see the other side -- since I fell victim to that interpretation myself above :-)
TimToady just have to figure out which way we want to answer the FAQ :) 16:45
probably have to drop offline for a bit now
pmichaud well, let me get a chance to clean it up over the next couple of weeks before we decide :)

moritz_ pmichaud, jnthn: with nopaste.snit.ch/20721 the ».meth parallel dispatch also works on RPAs is it the wrong approach? (feels a bit like it) 16:51
pmichaud it's wrong. 16:52
the correct solution is likely to add a .list method to RPA
moritz_ ok 16:53
pmichaud I'm not sure I want to be auto-flattening other foreign objects just yet
but also, every workaround that gets added in now to try to get .list and list() to behave is making the overall task of fixing/refactoring lists and iterators that much harder. 16:55

TimToady if that's what S really means there....

moritz_ I though S was "sequential", not "really lazy"
TimToady S is kinda fuzzy 17:28
I suspect it means different things to different operators
moritz_ jnthn: should it matter where in the setting the operator appears (as long as it's top level)?
TimToady but the fuzz could just be in my head

pmichaud: I've left the multi check as calling .multi though.
pmichaud wfm

pmichaud I'll start my refactor by seeing what it takes to move Positional into core
jnthn We *could* make it play nice with Parrot multis by doing a pir::isa check against MultiSub.
pmichaud: OK. Hopefully it's not too painful. 18:14
pmichaud: Associative wasn't, once I fixed the bug that stopped us doing augment to add a role.
pmichaud well, it's largely a question of whether we're able to compile the setting with a compiler that doesn't understand Positional
(since Positional will be in the setting instead of in the base compiler) 18:15
jnthn pmichaud: Ah, true.
pmichaud Associative is much less critical there, because it doesn't impact lists/arrays/flattening/etc.
moritz_ (offtopic: it never ceases to amaze me how long it takes to cook corn on the cob)
jnthn pmichaud: True. OTOH, I had a bit of fun from the fact that every method has a *%_ - which is something that does Associative. 18:16
pmichaud true. :-)
the other nastiness is that refactoring lists and positional and the like always breaks "make test" 18:17
jnthn Yes. :-(
pmichaud so it's a slow process to even get the basics going again
jnthn Not to mention make spectest.
moritz_ or compiling the setting :-)
jnthn Heh
Su-Shee looks at the long, long list of tests. did I really want DBI?
jnthn I hate it when compiling the setting breaks.
jnthn has spent lots of time working on things that can easily lead to that 18:18
pmichaud yay! all tests pass!
moritz_ like, uhm, multis? meta model? 18:19
jnthn !!
moritz_: Signatures. :)
moritz_: And those
pmichaud maybe I should stop here (i.e., immediately after doing git clone, that is)
jnthn pmichaud: That's moving moving Positional to ...oh, you didn't.
:-)
Now if only I could get all tests to pass on Win32. :-)
pmichaud stopping at this point is likely my only chance of having a successful day. 18:20
jnthn Aww.
moritz_ pushed Match + Array fix
pmichaud otherwise it's going to be a day of pain and torment.
jnthn I imagine said refactor is more than 1 day's effort.
pmichaud I'm hoping less than 3, though.

jnthn pmichaud: Associative comes *very* early in the bootstrap. 18:27
pmichaud jnthn: I'm guessing that when we run the base compiler to compile the settings, none of the subroutines have an Associative constraint.
and after compiling the settings, Associative is available?
(because it's early in the compile sequence?)
okay, I think Positional may be able to work the same.
jnthn pmichaud: All that actually matters is that Associative is declared in the setting before any methods are. 18:28
pmichaud: If you look at CORE_SOURCES, the ordering of a lot of that stuff is quite carefully done. :-)
pmichaud right -- I'll have to switch them around a bit anyway
jnthn It's a bit of a balancing act.
pmichaud Positional would probably need to be declared in the setting before any methods or subs 18:29
jnthn We have two things that help us a *lot* though.
pmichaud or anything that takes an @-parameter.
jnthn 1) Stubs are enough for the parser to be happy about the type name from there on in.
2) Sub and method signatures are lazily composed on the first call
So we can get away with quite a lot. 18:30

moritz_ Su-Shee: you should run 'make install' in rakudo, and then use the installed perl6 bin 19:04
isBEKaml Su-Shee: you should probably do a make install in your rakudo dir and append the executable's location to your $PATH
moritz_ right
isBEKaml what moritz_++ said.
moritz_ and what isBEKaml++ said :-)
Su-Shee I've added hard coded the path in the makefile which works but I'd like to have a proper setup. :)
ah make install works now? :) 19:05
moritz_ it did so for about half a year :-)
isBEKaml Su-Shee: you don't need to hard code in the make file. install by default installs to the current directory (as far as rakudo goes, not parrot)
pmichaud jnthn: interesting... in reviewing discussions from late Feb and early March, we speculated that the @-sigil really means "does Array" instead of just "does Positional"
Su-Shee isBEKaml: I know that. ;) 19:06
moritz_: how the hell should I know... I lost overview over like 45698 rakudos :)
jnthn pmichaud: I've heard it speculated as does Iterable too.
Su-Shee I should clean up. ;)
pmichaud I'm less inclined to buy that
isBEKaml Su-Shee: read Makefile? :)
Su-Shee isBEKaml: what for? ;) if all goes smoothly, I don't bother :) 19:07
jnthn pmichaud: Well, thing is, you can probably derive a Positional interface from being able to iterate something, but not vice versa so easily.
pmichaud the fundamental reason to want @ to mean "Array" is that people expect @-things to remember values 19:08
while Iterable doesn't imply that
jnthn Ah
Yes.
isBEKaml Su-Shee: :)
pmichaud still need to keep reading notes
19:08 BrowserUk left
Su-Shee ah. now I get proper, expected errors I actually want to have :) 19:08

sorear and got distracted before saying I started
TimToady it was not an ingressive progressive, I guess
pmichaud isBEKaml: they don't associate. But one of their elements might.
i.e., @array isn't Associative, but @array[$index] might be. 19:13

moritz_ what do I need to do to make hash() work in that case?

sorear What does it mean when :::: cursor_xact (20 lines of text) ? 21:55
colomon my quick thought is that it's probably not good as a default implementation, because (at least in theory) the Parrot versions we call should be about as fast as possible on a Parrot platform.
on the other hand, there's a very good argument to have a pure p6 version. 21:56
good both for ports and (at least potentially) for numeric types other than system floating point.

colomon The PIR probably boils down to a call to the underlying C library implementation.
lue Don't ask me why, but I feel that PIR should be in .pir files and P6 in .pl files. [However, I do see clearly why you'd spend 5 seconds typing inline PIR than 5 hours implementing a decent sine algorithm]
colomon lue: if you're just looking for something random to do in p6 that's math-related, it would be very interesting to try implementing a new type that does Numeric. Something like Hamiltonian numbers. 22:02
It wouldn't be something to go directly into p6, it would be an early module 22:03
