  • 5.12 will support each on arrays. So that would be:

    while (my ($num, $line) = each @foo) {
      if ($line =~ /corge/) {
        $bar{$num} = $line;
      }
    }

    You can have this right now with Aaron Crane's Array::Each::Override [cpan.org].

    • ...and really, that's much better, because otherwise you'd have to constantly copy $ into a lexical for nested loop. Too much vertical space taken!
