What is that, string and file modules? It usually doesn't look
like that in Lisp.

This reminds me of some other Lisp dialect where you'd have an
exclamation mark last if the function hade side-effects.
So maybe a question mark last is their way of doing our `-p'
(or vice versa depending on who was first).

While I don't want to make too big a thing of it, conventions
like these are probably better not to mix. (Ours look better,
also. Less disruptive.)
