Continuations and threads (was Re: Iterators & generators)

[Mike Fletcher]

Not being a CS person, maybe I can confuse the issue :) ...

A continuation is a suspended execution context, you get to a point and say
"can't/won't finish this now, I'll store the state (frame) and let other
execution contexts call me when I should continue".  When you want to resume
the context, you "call" the continuation, which resumes running the
suspended execution context at the next line after the call to suspend.

If I'm reading things right, there are methods on continuations which allow
for updating variables while not running the context, so you can pass
information into the context while it is suspended.

But that's just from me skimming through Christian's article :) .  I've been
known to miss important CS concepts before ;) .

Enjoy,
Mike

OK, that's informative.  So much for the differences between threads and
continuations.  But I'm still left wondering just what the heck
continuations are.  :)
