The last thing i remember from this discussion was spending a lot
of time trying to understand everyone's implementation schemes and
drawing little pictures (http://web.lfw.org/python/globals.html)
to describe them.

I never heard anything back about them, and the discussion on this
topic went suddenly silent after that.  Was there a correlation
(i hope not) or did everyone just get busy with other things?  I was
hoping that the figures would help us compare and evaluate the
various schemes.
