[Numpy-discussion] Should bool_ subclass int?

[CHOP: lots of examples]
It looks like bool_s could use some general rejiggering. Let me put forth a
concrete proposal that's based on matching bool_ behaviour to that of
Python's bools. There is another route that could be taken where bool_ and
bool are completely decoupled, but I'll skip over that for now since I don't
really think it's a good idea.
1. +,- are arithmetic operators and return ints not booleans
2. *,** are arithmetic operators on scalars and arrays and return ints
3. &,|,^ are the logical operators and return booleans.
4. *,** are defined on matrices to perform logical matrix
multiplication and exponation.
This seems like the simplest route towards something that is both internally
self consistent and consistent with Python.
