As an ex-compiler guy, I should have something wise to say about that.
Alas, I've never used a system that allowed more than poking new values into
vrbls, and the thought of any more than that makes me vaguely ill!  Oh,
that's right -- I'm vaguely ill anyway today.  Still-- oooooh -- the
problems.

This later got reduced to restarting the topmost function from scratch.
That has some attraction, especially on the bang-for-buck-o-meter.

What a pussy <wink>.  Really, overall continuations are much less trouble to
understand than threads -- there's only one function in the entire
interface!

OK.  So how do you feel about coroutines?  Would sure be nice to have *some*
way to get pseudo-parallel semantics regardless of OS.
