I am curious: why you recommend against this? Using the C-API through cython
seems more attractive than using the Cython-specific numpy features since
they need a specific number of dimensions (and I don't think they broadcast)
and don't seem that much easier. Are there hidden disadvantages to using the
C-API? Have I misunderstood something?
