Is RPython really that bad? Lack of generators seems like the only serious 
issue to me.

Unless we use Shed Skin to translate the RPython into C++. Or maybe we 
could write the code in Pyrex, generate C from that for CPython, then have 
a python script which strips out the type definitions to generate pure 
python for PyPy.


Don't trust the laws of men. Trust the laws of mathematics.
