Could you explain a bit more why you think this is the best path to  
follow?
Pyrex is kind of a dialect, so your extension modules would be nor  
python nor C, but a third language. Is this indeed easier to maintain?  
When you would like to use legacy C code for an extension, would you  
rewrite it in Cython? What are Cython's advantages compared to ctypes?

Cheers,
Joris
