I do not know if you are talking about first-class continuations or not, but
in languages which are stack-based first-class continuations are not trivial
to add. (By stack-based I mean that the procedure entry exit sequance
behaves in a stack-like fashion) In C the idea of setjmp/longjump comes as
close to continuations as one can get. Admittedly, this is not as elegant as
Scheme's notion of continuation but workable in concept.
