* masak submits rakudobug
<masak> now, are my expectations right in this case? could the above
code print "OH HAI"?
<Matt-W> masak​: I don't know if your expectations are correct
<Matt-W> Is :$.bar supposed to be like :bar($.bar)
<masak> aye.
<masak> that was my expectation.
<moritz_> I don't think so
<Matt-W> Because I wouldn't expect so without reading it somewhere
<moritz_> because $.bar is not parsed as a variable, but as a method call
<masak> moritz_​: does that matter?
<moritz_> it does matter, Perl 6 is all about syntax
<masak> and what about :$!bar, then?
<Matt-W> I would expect the same behaviour as $.bar
<Matt-W> whatever that happens to be...
<masak> rakudo​: sub foo(​:$bar) { say $bar }; class A { has $!bar;
method baz() { foo(​:$!bar) } }; A.new(​:bar<OH HAI>).baz
<p6eval> rakudo b19862​: OUTPUT«Symbol '$1bar' not predeclared in baz [...]
<masak> I still think Rakudo does the Wrong thing here.
<moritz_> $1bar?
<masak> there's no $1bar variable.
<masak> right.
<moritz_> that's a less-than-awesome error message
<Matt-W> At the very least
<moritz_> (hint, hint)
<masak> yes, it alone merits a bug report.
<masak> moritz_​: I'm writing it now. you're in it! :)
<Matt-W> It's either a Missing Feature or a less-than-awesome error message
<Matt-W> the question is which
<masak> Matt-W​: exactly.
<moritz_> well, the table in S06 for named arguments doesn't list it, I think
<masak> I see no reason why it shouldn't work.
<masak> same with $^placeholder variables, I'd say.
<Matt-W> I see no reason why it should
<moritz_> convenience would a good reason, no?
<Matt-W> Mmm
<masak> I think so.
<Matt-W> I can seen an argument for it
<masak> consistency, too.
<moritz_> Perl 6 is all about convenience; otherwise we'd still be
writing assembler code ;-)
<masak> it's not like the syntax is being used for something else.
