Thanks to Tom McDougal for bringing up something that bugs me a lot.
Cartier's fix is way better than nothing. But this is an important facility
and deserves some hacking.
With (setq *clear-mini-buffer* nil)
When you've got (foo (undefined-fn
then minibuffer still shows foo's arglist. It should say "UNDEFINED-FN is undefined.".
When you've got (foo (bar)
then minibuffer still shows bar's arglist, but should show foo's.
A really clever implementation would notice in
(let ((a ...)))
that A is not suppose to be a function. There are a finite but number of such situations
in Common Lisp.
Before the big fix, I vote for putting *clear-mini-buffer* on the Environment dialog
just under *ARGLIST-ON-SPACE*.
