Hey! If Stackless goes with GC, can we get 5 times "really"? :-))

I'm currently looking into that. Seems to be *very* possible
and *very* worthy to be done. Many cyclic issues with
continuations are much easier and probably more efficient
to solve with *the* GC at hand, similar to Mikecode Hackson's
observation.

It will become simpler, simpler and simpler.

Today I'm saying so. But I think there will come a time
where people are told "look, a continuation is as simple as 1+1",
and they'll say "sure? I thought a co is simpler."

That's not a continuation matter. The problem is to get
a really really really (really? :) good coroutine design
together that fits everybody's expectations. Expressing
them with continuation is just a homework. Doing the
right design is very hard.
