Stackless Python and Python 2.x

[Michael Abbott]

What's the current status of Stackless Python in relation to the developing 
Python 2.x implementation?

I can see that there's a patched version of Stackless Python for version 
2.0 (http://www.stackless.com/) and there's PEP 219 describing an 
inspiration for this idea.  However, I also see that PEP 219 is marked as 
deferred and that PEP 220 (which covers the details) contains a brief 
abstract only.

Of course, we now have generators (PEP 255) in Python 2.2, which takes us 
part of the way there, but the gap remains big!

So, my question is whether coroutines are likely to make it into Python in 
the forseeable future?
