[Numpy-discussion] Scalar math module is ready for testing

Here is an issue I am having with scalarmath:
>>> import numpy
>>> import numpy.core.scalarmath
>>> a = numpy.array(, 'h')
Traceback (most recent call last):
File "<stdin>", line 1, in ?
TypeError: unsupported operand type(s) for *: 'int' and 'int16scalar'
This happens because PyArray_CanCastSafely returns false for casting
from int to short. alter_scalars(int) fixes this, but I have lots of
non-numpy code that I don't want to behave differently.
