On the other hand, there is no need to enforce every Python implementation to do the full continuation support. In CPython, continuationmodule.c can be used for such purposes, and it can be used as a basement for coroutine and generator implementations. Using Guile's way to implement these would be a possible path for JPython.

Actually, you can't use Guile's way for JPython -- the guile folks are doing some low-level semi-portable stuff in C...

- incorporate Stackless into CPython, but don't demand it for every implementation

Again, I want to say I don't think there's a meaning for "for every implementation" -- Stackless is not part of the language definiton, it's part of the implementation. The whole Java/.NET is a red herring.

- implement coroutines and others with Stackless for CPython

I think that should be done in a third-party module. But hey, if Guido wants to maintain another module...

- do not make continuations a standard language feature until there is a portable way to get it everywhere

I'd got further and say "do not make continuations a standard language feature"

Still, I can't see the point with Java. There are enough C extension which are not available for JPython, but it is allowed to use them. Same with the continuationmodule, why does it need to exist for Java, in order to allow it for CPython?

My point exactly.
