[00​:09​:37] <lizmat> just found an inconsistency​:
[00​:09​:41] <lizmat> r​: my &foo; say &foo.WHAT
[00​:09​:44] <+camelia> rakudo-parrot 0cfe87, rakudo-jvm 882e33​: OUTPUT«(Any)␤»
[00​:09​:52] <lizmat> r​: sub a(​:&b) { say &b.WHAT }; a()
[00​:09​:55] <+camelia> rakudo-parrot 0cfe87, rakudo-jvm 882e33​: OUTPUT«(Callable)␤»
[00​:10​:20] <lizmat> a &foo variable is different from a &foo parameter?
[00​:10​:55] <lue> r​: my &foo; sub a(​:&b) { say &b.WHAT }; a(​:b(&foo));

[00​:11​:30] <lizmat> lue​: indeed
[00​:11​:47] <lizmat> r​: sub a(&b?) { say &b.WHAT }; a() # doesn't have to be a named parameter
[00​:11​:50] <+camelia> rakudo-parrot 0cfe87, rakudo-jvm 882e33​: OUTPUT«(Callable)␤»
[00​:11​:54] <lue> r​: my $igil; my @​rray; my %ash; my &ode; say $igil.WHAT; say @​rray.WHAT; say %ash.WHAT; say &ode.WHAT;

[00​:12​:07] <lue> $ and & have something in common :)
[00​:12​:35] <lizmat> but why would that be diffferent for parameters ?
[00​:12​:40] <lue> $ -> Any makes sense to me, & -> Any less so. (It should be & -> Callable IMO, like @​ -> Array or % -> Hash)
[00​:13​:38] <lue> r​: sub a($ig?, @​rr?, %as?, &od?) { say $ig.WHAT; say @​rr.WHAT; say %as.WHAT; say &od.WHAT }; a()
[00​:13​:41] <+camelia> rakudo-parrot 0cfe87, rakudo-jvm 882e33​: OUTPUT«(Any)␤(Array)␤(Hash)␤(Callable)␤»
[00​:13​:55] <lue> & is the only inconsistent one it seems.
[00​:14​:05] <lizmat> yup

From @lizmat

This most definitely has been fixed with tests

The RT System itself - Status changed from 'new' to 'open'

@lizmat - Status changed from 'open' to 'resolved'
