When I had some extra time on a plane I started to write up a 
PEP-like-thing. My proposal is that macros are expanded by the 
preprocessor and Pyrex works on the expanded output.

If a person WANTS to use a macro from Pyrex (evil!) then they just need 
to type-declare it manually. Usually the ratio of functions to macros is 
something like 20-1 so that is probably acceptable.
