Actually, can you tell me what's going on here:
my %words_lookup = (map { $_ => 1 } @words_to_look_for);
I build a hash called %words_lookup whose keys are the entries of
@words_to_look_for and all of its values are 1. See:
http://perldoc.perl.org/functions/map.html
That way I can tell if a word is in @words_to_look_for quickly by doing:
exists($words_lookup{$word}).

Shlomi Fish
That would be most helpful.
