I just looked at ctypes, and yes, that's exactly what I'm doing.  I want 
the structures definitions to be modified by C++ programmers and I find 
the metaclass mechanism much more readable and easy to modify (and it's 
not a lot of code to make everything work).  I agree everything can be 
done using normal Python code, but my goal here is really to make a 
pseudo-language to define our formats, and the pseudo-language is just a 
simpler solution than XML in my specific case.  Probably all cases of 
such using of metaclasses are like that...

Nicolas
