							         ^^^^^^^

   Continuations do not really support multitasking: they merely (:^)
   represent the flow of control within a single task. However, 
   there are several Lisp's which do support multi-tasking: Bertram Hallam's
   multi-lisp, QLisp by Gabriel and ?, and others I'm sure. (please forgive
   inaccuracies in the refs, I am not up to date on the topic). On a more
   practical level, there are the stack group's of the explorer (probably
   first done by symbolics).



sorry for the and/or.  engines are definitely designed with
multi-tasking support in mind.

as for continuations, it was my impression (untested) that it would
not be hard to implement coroutines with first-class continuations.
anyone care to demonstrate the matter either way?
