Current Perl documentation can be found at

Here is our local, out-dated (pre-5.6) version:

Both grep and map build a return list, regardless of their context. This means you're making Perl go to the trouble of building up a return list that you then just ignore. That's no way to treat a programming language, you insensitive scoundrel!
