think this addresses the
larger issue with large/infinite streams/generators, I'll certainly
use this trick for small lists.

My current approach aside, is there a better way?
Here's my workaround,
(define (call-n-times f n)
(define (helper f n lst)
(if (< n 1)
lst
(helper f (- n 1) (cons (f) lst
(helper f n '()))
(define (take-randoms k n)

Has anyone else gone down this road before? Also, Besides Eli's
paper, any general advice for Racket FFIs?

So far, no one has suggested a regexp. Why not,
(define (all-lower-case? s) (not (regexp-match? #rx"[A-Z]" s)))

Is racket-lang.org written in Racket? Also, where is the source for
planet.racket-lang.org?

. That aside, are there any papers that introduce
"inspectors"?
