Yes, please do not take my comments for a criticism of your approach. It seems 
well founded, a h*ll of a lot better than what we have right now it terms of 
maintenance. Beside, none of us on this list are responsible for the current 
design choice... so nobody will fight you if you improve the design!!!

According to the changes.txt of Numeric 21.0, Numeric now implements true 
division operatons relying on Python 2.2 whatever this means. I have no clue, 
but it seems like Numeric uses the new features of Python 2.2.

I don't use CVS Jython so I'll take your word for it. Does it mean that Jython 
now implements iterators? I seem to recall that it was the big change. 

How is Jython going along? Jython seems frozen as far as I can tell. Jython as 
it is, is good enough for my purposes, but if we are going to rely on it more 
heavily to keep up with Python, then we should know that it is doing well. 
The mailing list seems active, but I don't see many releases.

I have no clue. I have never used Numarray.
