Re: FW: How to avoid compiler warning `unused lexical variable' for `dolist' or `dotimes'?

Please don't do that: such a "dotimes + elt" is fine when iterating over
a *vector*, but when iterating over a list it means it'll take time O(n²)
since `elt` on a list takes time O(n).

So it's *much* better to use `dolist` (or `mapc` or ...) in that case.
