Lisp is a bit different, because it's always had only a very
few chars that aren't identifier chars, so you're used to seeing
identifiers with all sorts of junk in them. But in Python, you
tend to see anything that you don't recognise as a letter or
digit as "punctuation" and therefore non-identifier.
