NOT FINISHED
*/
#include "numpy/arrayobject.h"
#include "numpy/ufuncobject.h"
/* The general strategy is to
1) Make self the array scalar and "other" the other data-type
2) If both are the same data-type, then do a quick exit.
3) If other is another array scalar, then
a) If it can be cast then cast and calculate
b) Otherwise, return NotImplemented
(or call the appropriate function on other... ---
shortcut what Python will do anyway).
4) If other is a 0-d array
-- Cast it to an array scalar and do #3
5) If other is a Python scalar
-- Cast it to an array scalar and do #3
5) Go through the ufunc machinery for all other cases.
