Not critical but a definite bug:

(defun nil () (error "Nil")) => nil
(symbol-function nil) => (lambda nil (error "Nil"))
(nil) ?? (void-function nil)
(funcall nil) ?? (void-function nil)

(setf (symbol-function nil) '+)
(symbol-function nil) => +
(nil 1 2) ?? (void-function nil)
(funcall nil 1 2) ?? (void-function nil)

	Peace

Hmph. I thought this worked the first time I tried it, but now it seems
to cause build errors, so I've taken part of it out again (3fd4433),
pending further investigation.

How/when did you bump into this?


        Stefan "who decided it wasn't worth paying attention to that case
                when he made `nil` to mean unbound for `symbol-function`"

I figure out what was causing this problem in 61f8c23,
and re-applied the fset change in ffb1302.
