The Loaded Uzi

• I've seen this before, but never on a regular array

• Usually, you see something like this:

        $input = something;
        for $key (%hash) {
          if ($key eq $input) {
            do_something($hash{$key});
          }
        }

• Which should of course be:

        $input = something;
        do_something($hash{$input}) if exists $hash{$input};
