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

The third arg is different from "the expression after `dotimes`" in one
important respect: the third arg can refer to the iteration variable
which will contain the "last" value:

    (dotimes (i 10 i) nil)

will return 10.
So the warning comes when you use that 3rd arg but without referring to
the iteration variable: in that case, you could have put the result
*after* `dotimes` rather than putting it in the 3rd arg.
