Hi,


I recently test a piece of code written using call/cc on Guile and several
other Scheme implementations, but get different results. The code piece is
as follows:

(let ((n 0)
      (c (call/cc (lambda (k) k))))
  (display n)
  (newline)
  (set! n (+ n 1))
  (c c))

What I wanna do is try to print out the sequence of natural numbers using
call/cc. On Guile, it works well. But other implementations (Chicken,
Bigloo, Racket) all print out (an infinite sequence of) 0. I am puzzled. Any
idea?
