Comment(by mwiebe):

 To add my opinion here: I want this case to raise an exception by default
 based on the 'same_kind' casting rule. e.g.

 {{{
 >>> a = np.array([1,2,3,4])
 >>> a /= 1.5
 >>> a
 array([0, 1, 2, 2])
 >>> np.divide(a, 1.5, out=a, casting='same_kind')
 Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
 TypeError: ufunc 'divide' output (typecode 'd') could not be coerced to
 provided output parameter (typecode 'l') according to the casting rule
 'same_kind'
 }}}
