Funny you should bring up chop again.

In the classes I teach, the fact that chop acts on its arguments is one of the most difficult things for students to keep straight. I see people writing all the time:

It's precisely because chop is so different from the rest of Perl that people get it wrong. So I'm not in favor of encouraging people to write more things like chop.
