Thanks, your comments definitely helped me seperate and present the 
concepts better. I renamed the page and moved some stuff around; it can 
now be found here:

http://wiki.cython.org/enhancements/overlaypythonmodules
http://wiki.cython.org/enhancements/builtins

Clarity: It might be a matter of taste. The latter link is about 
something I think it makes the Cython language "less heavy" by removing 
a few special cases that's not allowed today. The idea in the former 
link I think will be a little complicated but as clear as the 
alternative I see; which is magical rewrites in the Cython compiler core 
and having to use seperate names for the type "c_numpy.ndarray" and the 
constructor "numpy.ndarray". (Using c_numpy is clearer from a low-level 
perspective but I think it adds a significant learning curve.)

Most of this is not that important now though (though some of it is 
NumPy-relevant). Nailing a good type argument syntax is more important 
and can be considered seperately from a usability perspective -- the 
very first response I got from the NumPy community on the specs was that 
"the ndarray constructor should take the same parameters as we are used 
to", when what they were looking at was really a parametrization of the 
ndarray type.
