Hi Stefan,

This is unfortunately not correct, e.g.

(cl-labels ((even (if (odd 5)
                      (lambda (x) (if (= x 0) t (odd (1- x))))
                    #'ignore))
            (odd  (lambda (x) (if (= x 0) nil (even (1- x))))))
         (list (even 42) (odd 42)))

~~> funcall: Symbol's function definition is void: nil

Only preceding definitions can be used in the EXP.

Dunno how useful it is at all that the EXPs can use any of the defined
functions.


Michael.
