   I do not believe that it is feasible to add continuations to C++ for
   any number of reasons, but I would be interested to hear the reactions
   in this community regarding their utility in object-oriented programming.

They are just as useful in object-oriented programming as in straight
Lisp or Scheme.  However, continuations in the Scheme style are only
useful if full support is provided for lexical scoping.  C and C++
have no lexical scoping whatsoever.  So I agree that it is not
feasible to add them to C++.  Even lexical scoping alone, with or
without continuations, would be a great benefit, but I'm sure I'll
never see it in C or C++.
