Please, no! the operator and functions should behave the same. I
certainly always expect them to. For instance, I often write code with
operators, then replace that with the functions so that i can add an
"out" parameter for performance reasons -- I would be very surprised if
the function were defined differently -- it would be a source of

I think consistency within numpy is more important that consistency with
python -- I expect differences like this from python (long integers,
different data types, etc)
