This begins to make it look what you want is array.array or nump.array.
Python's arrays don't support bitwise operations either, but numpy's do.
How much overlap is there between the three types?  Does it make sense to
consider that canonical underlying array type now (or in the near future,
sometime before the release of 3.0 final)?
