Thank you Alex!  Excellent pointers.

Thank you Hendrik. I guess I should have specified that I am interested in
how to implement first class serializable continuations, and to interface
with them.  As you point out, continuation passing style is simply never

A friend of mine was explaining that Microsoft's new Async C# offers a nice
interface programatic interface to continuations, where the compiler notices
the "yield" keyword, and automatically generates a finite state machine
where the current state is captured as a continuation, and then the
interface to the continuation is done via IEnumerable.  This sounds
elegant.  Has anyone compared it's ease of use to the gambit/scheme style
