Gowrsh.  I really should re-read CLtL2.

(let ((vars (some-ting))
      var)
  (while (setq var (pop vars))
    ...))

which I usually write, vs

(dolist (var (some-thing))
   ...)

And the latter is even a macro in cl-macs that expands to nice
Emacs-lisp bytecodes.

(And the first form even assumes that there are no non-nil elements in
the list.  Which is true everywhere I use it, but that makes the
dolist thing even more elegant.)
