Hi all,
From what I understand about call/cc, when a saved continuation is
invoked, the current continuation should be discarded. So I expected the
following program to just print `stop?' once; however, it doesn't stop.
Welcome to DrScheme, version 4.2.4 [3m].
Language: Pretty Big; memory limit: 128 megabytes.
> (define stop
(let ((k (call-with-current-continuation (lambda (k) k))))
(lambda ()
(display "stop?\n")
(k k))))
> (begin (stop) (stop) 42)
stop?
stop?
42
>
So is this an error in my understanding of call/cc or in DrScheme?
Regards,
Bas
