Stackless definitely appeals to me from a coolness factor, though I
don't know how much I'd use those new capabilities that it allows.
The ability to embed Python on hardware that might otherwise not be
possible without Stackless is also an interesting thing to explore.

Maybe a PEP isn't the right venue, but the semantics and externally
visible effects of Stackless need to be documented.  What if JPython
or Python .NET wanted to adopt those same semantics, either by doing
their implementation's equivalent of Stackless or by some other means?
We can't even think about doing that without a clear and complete
specification.

Personally, I don't see Stackless making it into 2.0 and possibly not
2.x.  But I agree it is something to seriously consider for Py3K.
