Lisp "assumed special" warnings

Lisp "assumed special" warnings

Lisp "assumed special" warnings

I'm getting "assumed special" compiler warings for my program in Common Lisp.
Eg. the following code
(defun POSSIBLE-MOVES (state)
(let ((moves nil))
(if (null state) (return moves))
(cond (eql '- (first state))  (append moves (first state)) (POSSIBLE-MOVES (rest state))
(t (POSSIBLE-MOVES (rest state))))

generates the following warnings

;;;*** Warning in POSSIBLE-MOVES: EQL assumed special
;;;*** Warning in POSSIBLE-MOVES: APPEND assumed special
;;;*** Warning in POSSIBLE-MOVES: POSSIBLE-MOVES assumed special

when I load the file containing this code

I'm a little new to this. Please let me know what's going on. Thanks, ~Vika

RE: Lisp "assumed special" warnings

This would be better suited for the common lisp forum.

That said, you should look more closely at the way to use COND.
