A procedural suggestion: let's have *two* PEPs, one for Huaiyu's
proposal, one for Greg's.  Each PEP should in its introduction briefly
mention the other as an alternative.  I don't generally recommend that
alternative proposals develop separate PEPs, but in this case the
potential impact on Python is so large that I think it's the only way
to proceed that doesn't give one group an unfair advantage over the
other.

I haven't had the time to read either proposal yet, so I can't comment
on their (in)compatibility, but I would surmise that at most one can
be accepted -- with the emphasis on *at most* (possibly neither is
ready for prime time), and with the understanding that each proposal
may be able to borrow ideas or code from the other anyway.
