The only use it makes of the element type isto speed things up a bit by extracting bound methods. So the typed-nessis not an essential feature of its functionality, just somethingrequired to support an optimisation.Extended to handle the various operator methods, this might be a usefulthing to have around. In conjunction with array.array, it could providea kind of "numpy lite" for when depending on full-blown numpy would seemlike overkill.-- Greg
