Ah, ok. Then yeah, I think you are supposed to loop through. ;) I'm
not sure that rep really needs a position function -- in most cases it's
just going to encourage non-lispy lisp programming, I think. In those
situations where you need one just include something like this:
(define (position item l)
(let loop ((rest l)
(i 0))
(if (equal item (car rest))
i
(loop (cdr rest) (1+ i)))))
Perhaps equal should be eq, depending on how you're using it...?
