Now I'm confused. As an interested observer, It seems to me that there 
is only one thing that is keeping users of Numeric from switching to 

"Performance with many small arrays"

Which seems to boil down to:

"Time to create a new array"

There are other small details, but from following the discussion, that 
seems to be the only show stopper. I understood that the goal of 
Numeric3 was to exactly solve that problem, while still getting all the 
nifty benefits of numarray.

Another nit: "speed" in not one goal. I understand that one of the goals 
of numarray was top performance for very large arrays. In fact, it's 
ironic that someone discovered that it was a safety check in Numeric 
that was causing it to be slower than Numarray with large arrays.
