Overloading '*' and '**' while convenient does have consequences. It would be nice if we could have a few more infix operators in Python to allow separation of element-by-element calculations and "dot- product" calculations.
http://www.python.org/dev/peps/pep-0225/ was considered and rejected. But that was in 2000...
While I don't have any spare cycles to push it forward and we are already far along on the NumPy to 3.0, I had wondered if we couldn't use the leverage of Python core developers wanting NumPy to be ported to Python 3 to actually add a few more infix operators to the language.
I don't think that stands a chance: http://www.python.org/dev/peps/pep-3003/
Frankly, I still think we should move forward. It will take us as long as the moratorium is in effect to figure out what operators we want anyway and we can do things like put attributes on arrays in the meantime to implement the infix operators we think we need. It's too bad we don't have more of a voice with the Python core team. This is our fault of course (we don't have people with spare cycles to spend the time interfacing), but it's still too bad. -Travis
