Interesting.  It's dated a couple weeks ago and has obviously been in
the works for a while.  There's a working implementation which I'd think
means it's outside the idea phase.

But it's so much cleaner than the existing generator stuff and can
pretty much replace it.  That is the kind of change that Python 3 really
should have been about.

I might take a look at the list archive.  I don't think I could deal
with actually receiving the mailings and trying to keep up with them.

Neat :).  This paper about Lua coroutines is good and if it hasn't been
part of the PEP discussion and looks relevant, you might want to post it
there:
