| Yah, I had to code this one myself.  I don't know if a function like

[code deleted]

why not just:

(defun rls-read-number ()
  "read a number from the keyboard"
  (call-interactively
   (function (lambda (arg) (interactive "n") arg))))

Okay, so, it's cheating. :-)

Just another GNU emacs hacker,
