Comment (by craigcitro):
New version of the patch. So this adds one additional Python/C API call,
but gets a 10% speedup for the case of `M[i,j]`, which I think is
worthwhile. Furthermore, it's only necessary because this is a case where
Cython doesn't do enough specific optimization for us -- one day, when
Cython gets smarter, we can clean this up more.
Also fixed a bug in matrix indexing with tuples, and added a doctest for
that case.
