r30136: $ ./perl6 -e '$/' # works $ ./perl6 -e '"hi" ~~ /(i)/; $0' # works $ ./perl6 -e '$0' # fails (in a strange way) get_pmc_keyed() not implemented in class 'Undef' [...] I don't know whether the failure should eventually be silent or loud, but I'm pretty sure it shouldn't involve get_pmc_keyed(). It clearly has something to do with indexing, since $0 is essentially sugar for $/[0]. The same problem reoccurs when indexing other, non-special scalars: $ ./perl6 -e 'my @a; @a[0]' # works $ ./perl6 -e 'my $a; $a[0]' # same problem get_pmc_keyed() not implemented in class 'Undef' [...] Perl 5's motto here seems to be complaining as little as possible. $ perl -Mstrict -we 'my $a; $a->[0]' Useless use of array element in void context at -e line 1. $ perl -Mstrict -we 'my $a; my $b = $a->[0]' $ perl -Mstrict -we 'my $a; print $a->[0]' Use of uninitialized value in print at -e line 1.
