You know there is one and only one correct value that you are
supposed to use in the program, only to compute that you use
a loop, so the "you do want the variable(s) to contain
different values at different times" is only true in terms of
the computation of the final value, if you follow. But maybe
that qualifies?

I know right?

Yes, but maybe you really do want to avoid that even more...

Nah, I think `setq' in loops are the exception that confirms
the other rule, that one should only use it for global vars.

And when should you use global vars?

When they already exist :)
