I think the underlying problem with continuations en-the-large is
that too much is in the continuation--leading to unnecessary over-
head.

Does a continuation in a block structured language NEED everything
on the block-stack, or is it more like 2-10 variables at rather
well defined locations ?? more like a functor than a continuation.

When I was writing real time coroutines on a PDP-11 I rarely needed
more than 2-3 variables and the addressing modes allowed for the
coroutine call and return to be simple PDP-11 instructions with
no more overhead than a normal subroutine call. (1975-77)
