We can start by reviewing the reasons for having separate
PyNumber/PySequence/PyMappingMethods
structures.  I believe that one of the reasons is that many types need to
allocate only one of the three.  Numpy arrays, IIRC, allocate all three.  A
dedicated PyArrayMethods struct can replace some if not all of these
allocations.
