Thanks. I need some more time to get a better feeling for components before I
can suggest an API. At the moment, I vaguely see that the component call stack
is close to orthogonal to the */cc call stack (it perhaps is not due to
backtracking and such). A wild guess: perhaps you could switch from the
functional view (call/answer) to a data-structure view (push/pop/embed, etc,
perhaps even typed) in the EOPL way if you wanted a fuller control over
components. For example, a JUMP would correspond to removing a portion of the
stack.
