    no need to wait it's just another syntax for my $sub =sub {}, just w/o the need to do dereferencing and occupying a scalar variable.

    from Re: foreach-loop-local var in sub:

    use strict;
use warnings;

foreach (0, 1) {
    my $i = $_;
    my $print = sub {
      print $i;
    };
    $print->();          # 0,1
}

      Which is what I use all the time now ;) But it feels kinda hacky, even though it works and even though it's actually documented behaviour. Getting "real" lexically scoped subroutines would feel less work-aroundish.
