I agree. The explanation that "a continuation represents the rest of
the program" is utterly useless as a pedagogic device. It didn't help
me understand continuations one bit, either. I still shudder when
people describe them that way.
So, how about we got about this in two steps. First, take a look at
the description of SEND/SUSPEND in
(I'm assuming that you have at least the slightest understanding of
Web programming.) If you want, you can download and play with the
server yourself to build your intuition.
Once you have some grasp for SEND/SUSPEND (it's not that hard, so
don't let this daunt you), let me know. I'll explain CALL/CC to you
in terms of it.
