Here's a cleaner snippet to achieve the same behaviour, now using
function-key-map :

(dotimes (i 10)
  (dolist (prefix (list "M" "C"))
    (define-key function-key-map
      (kbd (format "<%s-kp-%s>" prefix i))
      (kbd (format "%s-%d" prefix i)))))

Below is a patch to achieve this from simple.el.

diff --git a/lisp/simple.el b/lisp/simple.el
