Well, numarray won't be updating much any more, and almost certainly won't be
addressing the fundamental problems with >32-bit arrays like numpy has. So go
for numpy.


That said, I don't think many people have actually been using >32-bit arrays
with numpy, yet, so there are probably still some issues to be worked out.

Disclaimer: I am a numpy developer.
