BTW, how is self-recursion expressed? These don't work in Scheme:

(let ((! (lambda (n) (if (<= n 1) 1 (* n (! (- n 1)))))))
   (! 10))

(let* ((! (lambda (n) (if (<= n 1) 1 (* n (! (- n 1)))))))
   (! 10))

We need this:

(letrec ((! (lambda (n) (if (<= n 1) 1 (* n (! (- n 1)))))))
   (! 10))

Would you need this:

(let-values (((!) (using ! (lambda (n) (if (<= n 1) 1 (* n (! (- n 1))))))))
   (! 10))
