Python 2.0 and Stackless

[Jeremy Hylton]

The official word: 

We will not be merging Stackless Python before the Python 2.0 release.
We have no plans to integrate it after the 2.0 release, but post 2.0
plans are less definite.

We would not consider adding Stackless code without a detailed PEP
that describes the specific changes.  (If you're not familiar with
PEPs, see http://python.sourceforge.net/peps/.)

My personal opinion: 

I would be surprised if Guido agreed to merge in code from the
stackless variant before Python 3000.  The biggest problems are
compatibility with JPython and the effects on the Python C API.
Neither of these problems are insurmountable, but they are hard.

When design work begins on Python 3000, I expect an opportunity to
consider this issue without compatibilty concerns.
