Agreed.  The problem is, in lisp, AFAICT, "well" or even "correctly"
is never *finally* determined.


(defun foo (x) (declare (fixnum x)) x)
(compile 'foo)
(defun bar (x) (foo x))
(compile 'bar)
(setf (symbol-function 'foo) (lambda nil nil))
(setf (symbol-function 'foo) (compile nil (lambda nil nil)))

Flexibility has its price.

Take care,
