Odd feature of perl5:
sub bar { &foo }
sub foo { print @_ }
print bar("It's Mmmmmaaaaagic!");
When foo() is called as &foo with no parens and no arguments, it
inherits @_ from it's caller.
This might have been originally introduced as an efficient way to pass
huge sets of arguments without copying before references were
introduced, but that's not a problem anymore. foo(@_) or goto &foo
works just fine.
I can't think of any reason why this feature is useful anymore, and it
can be a really confusing behavior, so what say we kill it in Perl 6?
