"...We haven't learned "map" or "grep" yet..."

What does you discourage from reading the friendly manual and learning it by yourself?

Some sketch written in a hurry for your further inspiration:

#!/usr/bin/env perl use strict; use warnings; use Test::More; use Data::Dump; my @colors = qw(red green blue yellow pink purple brown); my @drop = qw(pink brown); my @expected = qw(red green blue yellow purple); my $regex = join "|", @drop; my @result = grep {!/$regex/} @colors; is($regex, q(pink|brown), q(Regex seems to be OK!)); is(@result, @expected, qq(Heureka!)); done_testing(); dd \@drop; dd $regex; dd \@colors; dd \@result; __END__

It's not carefully tested. And may be there is a better solution. Best regards, Karl
