Do you mean have register each of the 21 different types of arrays as a
new type object? Hmm. That is an interesting idea. I'm a little
worried about implications for having the arrays behave together, though
it would make it more straightforward to define specific mixed
operations. This does deserve a little more thought.

Do you think this would fly with the Python folks. Counting the
suggestion above, we would be encouraging the creation of 39 new types
to the Python core. My current count shows the current number of types
as 35 so we would basically double that. This doesn't have to matter,
but I'd have to hear how Guido feels about something like that.

That would be ideal. But, I'm not sure what kind of chance we have
