My favorite module for this kind of thing is List::Comprehensions:

#! perl -slw use strict; use List::Comprehensions; my @a1 = qw(0 1 2 3 4); my @a2 = qw(0 1 2 3 4 5 6 7 8); my @a3 = qw(0 1); my @a4 = qw(0 1 2 3 4 5); comp1{ print "@_"; } \@a1, \@a2, \@a3, \@a4;

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
