Since when has numpy used Cython? I specifically remember a rather
involved discussion thread on numpy-discussion about the pros-and-cons of
including cython. Now, SciPy on the other hand, does utilize Cython in
some spots IIRC, but does it in a way that it isn't even required for the
developers to have cython installed to build from source.
I would not be against such an approach. Much of the C/C++ stuff is rarely
touched. If we have some source cython that is used to generate C/C++
source code that is packaged in the same way as the current code is, I
would have no problem with that. Given that matplotlib is such a
fundamental tool in the ecosystem, I want to make sure that the decisions
we make are ones that improves our packaging situation.
