What's bad about Python?

Because I'm learning it, almost done through the tutorial, and it looks great.

Sorry for bothering you again (and for bumping this awful thread), but I would like to ask you something.  If given the shift/reset primitives in your Lispy language of choice, how would you implement (make-generator f) such that:

(define g
    (make-generator
        (lambda (yield)
            (map yield '(1 2 3 4 5)))))

(g) ; should print 1
(g) ; should print 2
(g) ; should print 3

It's been haunting me for days now.
