Same with wxPython. If you draw a line with wxPython, and pass in a 
(N,2) array for the point coordinates, it's slower than a list of 
tuples. With numarray, a LOT slower. If the core multiarray type were in 
the standard lib, wxPython would have code to use them and be much 
faster for this kind of thing.

No, but I'd also love to see at least the basic math operations in the 
core too. There are so many questions on c.l.p (and other places) that 
just cry out for a NumPy solution!
