Kaiepi there's syntax for this, but i'm not sure if it does what i hope it would: 03:44
Xliff Yeah. Bugging me now, too. 03:45
Kaiepi m: role Foo[::T] { }; sub foo(::T Foo[T] $) { T }; say foo Foo[Int]
camelia Cannot find method 'ACCEPTS' on object of type T
in sub foo at <tmp> line 1
in block <unit> at <tmp> line 1
Kaiepi ah, i forgot Metamodel::CurriedRoleHOW doesn't know how to deal with that
when i made it so it did the signature binder complained about an inconsistent bind result, so i wasn't sure how to proceed from there
Xliff Ah. Well, I'm just curious as to how and when the "::T" for is used, and it is not documented. 03:47
Kaiepi m: sub foo(::T $) { T }; say foo 1 03:48
camelia (Int)
Kaiepi it makes a lexical named T that gets filled out with the type of whatever you give it afaik
only problem is you can't do this: 03:49
m: sub foo(::T $ --> T) { }; say foo 1
camelia Nil
Kaiepi m: sub foo(::T $ --> T) { T }; say foo 1
camelia Died with X::TypeCheck::Return

evalable6 (Int Str Rat)
Xliff Oh my.
Kaiepi if this doesn't work i think the return type thing is a bug: 03:50
m: role Foo[::T] { method parameter(--> T) { T } }; say Foo[Int].parameter
camelia Died with X::TypeCheck::Return
in method parameter at <tmp> line 1

Xliff Kaiepi: In my uninformed opinion, I think you might be right. 03:52
ZzZombo It's documented, it's type capture.
Xliff ZzZombo: Where, pls?
ZzZombo Search "type capture"? 03:53
Kaiepi fun fact: type parameters are signatures so you can give types named parameters 04:00

Kaiepi you won't be able to get them from instances of that role, though

Kaiepi wait, that uses a Metamodel::ConcreteRoleHOW, not a Metamodel::CurriedRoleHOW, maybe you can 04:08

Kaiepi yeah i was misreading what Metamodel::ParametricRoleHOW.specialize and .specialize_with do 04:09

I guess you want to put rakudoweekly.blog/blog-feed/ in your bookmarks

lizmat I tweet and post the actual weekly's URL on channel
Juerd Oh, I have no trouble finding it :) 14:18
lizmat ok :-) *phew*
Juerd It's just that I go to the .blog/ url, and sometimes get distracted before clicking blog feed :)

Xliff What exit code does raku return when die is invoked? 21:22
El_Che it looks like 1 21:23
Xliff El_Che: How are you checking that?
El_Che perl -e 'die' ; echo $? 21:24
perl6 -e 'die' ; echo $?
Xliff Hrm. Was using &&
El_Che && only executes if success
funy enough perl (5) does return 255 21:25
Grinnz (which is 0 in bash)
Altai-man_ .oO ( can I use funny images in advent article ) 21:26
Xliff OK. So I want to get the error code of a qx[]... do I need Proc::Async? 21:28
Grinnz El_Che: it actually exits with the value of $! if it's set to something, $? if it's set by a DESTROY or END, and 255 otherwise 21:29
because of the use of $! it's a little unreliable 21:30
the only guarantee is it won't be zero 21:31
(unless something sets $? to 0... but then that's your own fault :P) 21:32
Xliff Actually... CAN you get an error code from a qx[]'d command? $! isn't set
Grinnz $! is for errno, not exit codes
Xliff So what is exit code? 21:33
Grinnz if it's the same as perl 5, $?
Xliff Unsupported use of $? variable; in Perl 6 please use $! for handling child errors also
Grinnz interesting
Xliff Yes. It is.
Grinnz those are two quite distinct cases :| 21:34
i guess that raku is further from the syscalls to set $!?
Xliff Hrm. I might need shell
