Python doesn't require __add__ to be associative, so this should not be used as a general sum replacement. But if you know that you're adding floating point numbers you can use whatever algorithm best fits you. Or use numpy arrays; I think they implement Kahan summation or a similar algorithm.
No, we do a straightforward sum, too.
