I don't understand the C++ part. How many useful python modules use C++ 
? For a start, my understanding is that python itself (interprter + 
stdlib) do not use C++ at all. Wrapping C++ in any language other than 
itself is a pain anyway :)

I am personally interested in two things: being able to use any pure 
python extension, and numerical code (I am a heavy user and sometimes 
contributor to numpy/scipy). I don't think I am alone in this niche. For 
example, someone on the numpy-discussion list asked about being able to 
use numpy from iron python:

http://groups.google.com/group/c-extensions-for-ironpython/browse_thread/thread/88102263f8586fd0

what can be done about that ? Since I don't understand how pypy can 
use/intend to use c-based extensions (I thought ctypes was the way, but 
it looks like I misunderstood things), I am not sure what the 
possibilities are *now*.

cheers,

David
