Subject: fif function from On Lisp

Hi folks.
For some reason this function from On Lisp doesn't work:
(defun fif (a b &optional c)
'(lambda (x)
(if (funcall a x)
(funcall b x)
(unless (null c) (funcall c x)))))
I should be able to call it like this:
(mapcar (fif 'zerop '1+ 1-) '(0 1 2 3) => (1 0 1 2)
but i'm probably missing something that is differs from Common Lisp to
Elisp.
Thanks in advance,
weber
