I have an example here:

http://starship.python.net/crew/mwh/hacks/amb.py

and (the same, but more bare-bones) here:

http://starship.python.net/crew/mwh/hacks/short_amb.py

I'd admit to them not being the easiest bits of code in the world to
understand, but if you stare at them long enough they might give you
some idea of the power and flexibility of continuations.
