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
