It seems that it is partly a cython problem. If py3k can be done for
numpy 1.5, I wonder if we should focus on making incompatible numpy
1.6 (or 2.0 :) ), with an emphasis on making the C api more robust
about those changes, using opaque pointer, functions, etc...
Basically, implementing something like PEP 384, but for numpy.
As numpy becomes more and more used as a basic for so many softwares,
I feel like the current situation is hurting numpy users quite badly.
Maybe I am overestimate the problem, though ?
