More Python craziness

In [6]: print None or 0
0

In [7]: print 0 or None
None

Numpy any is consistent with python when considered as logical_or.reduce

In [13]: print array([0, None]).any()
None

In [14]: print array([None, 0]).any()
0

This appears to be an __ror__, __or__ inconsistency in python. Note that
None possesses neither of those operators.
