timotimo the spesh log or the behaviour?
MasterDuke behavior
the infini-looping happens around 2k instead of 6k
but lower counts still give `Too few positionals passed; expected 3 arguments but got 2 at SETTING::src/core/Mu.pm6:582 (/home/dan/Source/perl6/install/share/perl6/runtime/CORE.setting.moarvm:gistseen)` 00:13

01:33 Kaiepi left
timotimo hm, it might be that the way PseudoStash gets the frames in question is sensitive to inlining of the frame that calls it 01:37
so the instructions for PseudoStash, like ctx* instructions, wouldn't matter as much with regards to their inlining behaviour 01:38

samcv ok question for people. currently the ~& (string AND op) performs differently than the ~^ or ~| op in that the ~& op's result is the length of the shortest string 04:44
while the other two ops, the result is the length of the longest string 04:45
because ~& op, i'd just end up being null's, so i guess it just shortens it. but does this make sense to have them act differently 04:47
though i guess it's specced so. i have to leave it as is

so, do we have a way to find to what PseudoStash we're exporting to when we'er inside an EXPORT sub ? 11:31
jnthn moritz timotimo Zoffix ^^^ 11:32
moritz I'm not aware of one, but that doesn't mean much 11:33
jnthn lizmat: Pretty sure there's no way to do that. 12:01
lizmat jnthn: yeah, slowly coming to that conclusion 12:02
what I want to do is to bind to $_ of the scope we're exporting to
jnthn o.O 12:04
Can't you just stick a `$_` into the Map returned by EXPORT?
Maybe that's a redecl error though
lizmat yup 12:05
that's what I'm trying to prevent
and I can't CATCH the error either :-(
jnthn Well no, because you've already returned the Map by that point :)
lizmat FWIW, I'm trying to port metacpan.org/pod/Env to Perl 6 and handling the case of %*ENV<_> 12:06
jnthn That'd be an...interesting...choice of env var name :P 12:08
lizmat it's pretty common in shells
it's usually the last command you've executed in the shell ? 12:09
m: dd %*ENV<_>
camelia Str <element> = "/home/camelia/perl5/perlbrew/perls/perl-5.20.1/bin/perl"
jnthn heh, wow :)
TIL 12:10
I'm doubtful that getting hold of the pseudostash would actually be a solution here though
Compile-time bindings don't actually quite work that way
lizmat so I wouldn't have been able to bind to the <$_> anyway, is what you're saying? 12:13
m: $_ = 42; sub a() { CALLERS::<$_> := 666 }; a; dd $_ # guess not 12:14
camelia This case of binding is not yet implemented
in sub a at <tmp> line 1
in block <unit> at <tmp> line 1
lizmat ok, thanks for thinking about it... will circumvent by prefixing names with "env_" 12:15
which would be read better anyway
jnthn Honestly, it's one of those places where I'd just say "if you want 'use Env qw($FOO $BAR)', just write 'my (:$FOO, :$BAR, *%) := %*ENV;'" :P 12:16
lizmat I will put that in the pod :-) 12:17

Rakudo expects additional parameters (peer-host, peer-port, socket-host, socket-port) in async sockets since commit 76af17a8b1. This set of changes tries to port github.com/MoarVM/MoarVM/commit/5e94da0 to the JVM backend and makes most tests from S32-io/IO-Socket-Async.t pass.

jnthn nine: An object has one representation 19:22
nine So I'm gonna have to figure out how to actually get that attribute storage working 19:23
jnthn What're you trying to do? :)
jnthn can't figure it out from the questions 19:24
nine I'm trying to give the wrapper classes Inline::Perl5 creates for Perl 5 classes a new meta class. This should give me more control over e.g. the method cache. With that I can simply add methods to the cache as I discover them through usage at runtime. 19:26
jnthn Following so far. What repr does the wrapper class have today? 19:30
Hm, and are you wanting an attribute on the object to hang the cache off? I'd maybe expect the method cache to live in the meta class... 19:32
nine As of github.com/niner/Inline-Perl5/comm...7b00caf8e2 wrapper classes are plain standard P6opaque classes which do the Inline::Perl5::Package role: github.com/niner/Inline-Perl5/blob...ackage.pm6
jnthn Ah, OK 19:33
nine The method cache is in an instance of the meta class. The only data those wrapper classes have is the pointer to an underying Perl 5 object. Hence the idea to use a CPointer repr. But then classes inheriting from such a wrapper won't be able to have attributes anymore
jnthn Ah, I see 19:34
Yeah, probably they want to have an attribute containing the CPointer instead 19:35
nine On current master, objects passed from Perl 5 to Perl 6 are all wrapped by Inline::Perl5::Object instances. And optimized candidates for discovered methods are added to those objects by mixing in roles: github.com/niner/Inline-Perl5/blob...ct.pm6#L32
jnthn I guess all the roles get costly with time :) 19:36
nine Not to mention that it's just a terrible hack :)
jnthn That too. Are you going to do the method caching by using the built-in method cache mechanism? 19:37
I think Metamodel::Primitives exposes something to update that
Doing that should mean spesh can resolve the method dispatches 19:38
nine Yep, Metamodel::Primitives makes this job a lot easier :) I'm just discovering the missing parts. E.g. the callers of .method_table all expect it to return a VMHash which Perl 6 code has a bit of a hard time doing
jnthn Ah.
Yeah. 19:39
nine And issues like getting a "This representation (Null) does not support associative access (for type VMNull)" in github.com/rakudo/rakudo/blob/mast...er.nqp#L12
Which I suspect is because %!attribute_lookup is not automatically initialized when a Perl 6 class does the Perl6::Metamodel::AttributeContainer role. 19:40
Nope....still P6opaque: no such attribute '$!wrapped-perl5-object' on type Foo in a Foo when trying to bind a value 19:57
Despite doing Metamodel::AttributeContainer and self.add_attribute to add that attribute and running self.compose_attributes($type) later on 19:58
Oooh...sprinkling some nqp::decont in compose_repr helps 20:20
