in thread Finding list elements in other lists.

I like your package solution, as well as the arguments for it. This package can easily be extended to work for any number of arrays, not only two. The calling code stays the same.
package All_In; use strict; use warnings; sub new { my $class = shift; my $self = []; for my $aref (@_) { my %h; @h{ @$aref } = (); push @$self, \%h; } bless $self, $class; } sub qualify { my $self = shift; for my $href (@$self) { return 0 if ! grep { exists $href->{$_} } @_; } return 1; } 1;

[Corion]: Hi marto!
[Corion]: The fun show at $work continues, as The Big Project is now in its second week of frantic live-bugfixing and weekend releases where nobody knows what went live. Nothing has been tested anyway.

Corion watches from the sidelines. Or rather, from behind, as my system only gets output from that process and my programs adhere strictly to the GIGO design principle.
[erix]: ah, that's nice to hear Corion :)
