19:31 <masak> PerlJam: yes. it's a bug by the parsing principles of Perl 6, I would say.
19:31 <masak> PerlJam: as in, %h should be defined by that point.
19:31 <masak> s/defined/declared/
19:32 <masak> that's why something like this works:
19:32 <masak> m: my %h = %h; say %h

19:33 -!- lizmat [~firstname.lastname@example.org] has joined #perl6
19:34 <lizmat> PerlJam: could you rakudobug that?
19:34 <retupmoca> oh, that's interesting
19:34 <retupmoca> m: my $x = $x.^name; say $x; say $x.^name;

19:35 <jnthn> PerlJam, lizmat: I think it's 'cus the traits are part of the declaration...
19:36 <jnthn> And until we know there's no "is FooType" trait there, we don't actually know what container to install.
19:36 -!- lvfjf [~chatzilla@gateway/tor-sasl/lvfjf] has joined #perl6
19:36 <jnthn> So it's kinda a can of worms to open.
19:36 <lizmat> ok... one of those things then...
19:36 <jnthn> "of" is similar
19:36 <PerlJam> sure, but the name %h is already in existence, so "Variable not declared" is LTA
