Well that is not too surprising.  ;-)

>>> isinstance(N.int32,int)
False

But the following was surprising to me,
which is surely what you meant to explain:

>>> isinstance(N.int32(0),int)
True
>>> isinstance(N.int64(0),int)
False

So, why the difference here?
Does it go away when Python's difference
between int and long goes away?

Thanks,
