Not sure what you mean here - I was referring to using existing Python 2 
code in Python 3 projects, and vice versa.

The Cython experience is definitely interesting: it's good to know there 
is some experience with this problem. My hope is that you can come up 
with some sensible rules and fix the rest with a few annotations (in a 
separate module informing the rest, or included in the codebase itself) 
for the ambiguous cases.

If there's any native language that it should be easy to generate 
bindings for in Python it should be Python, right? :)

Anyway, separate from the binding, I'm wondering about the challenge of 
two Pythons in one runtime - how hard would it be to generate this with 
the current PyPy? (imagining two different Python interpreters were 
available)

Regards,
