AFAIK subr.el's dolist and dotimes are 100% compatible with
CL's definition.  Of course, if you want to call `return' in there,
you'll need to define `return', which is only provided by CL so you need
to (require 'cl).

I'd reconsider it only if someone can show me reasonable code that works
without error both with CL loaded and without CL loaded and yet returns
different results.
