# Re: Multiple arguments to mapcar?

Pascal: Here's a neat example of using of loop to solve a well-understood problem in a nonobvious way...

(defun primes-below-limit (limit)

(cons 2

(loop for i from 3 by 2 below limit

unless (loop for p in primes

when (integerp (/ i p)) return t)

collect i into primes

finally (return primes))))

I think this is portable and correct, provided limit >= 2.
