I agree. An analysis should be done in order to see if it is better to
concentrate in getting numarray better for small arrays or in having several
array implementations. The problem is if numarray cannot be enhanced enough
because of design problems, although I would bet that something can be done
in order to get it close to Numeric performance. And I guess quite a bit
people on this list would be happy to collaborate in some way or another so
as to achieve this goal.

However, as Perry says, in order to do this analysis, an amount of the
needed speed-up should be estimated first.

I personaly feel that it would worth the effort to go and try to optimize
the small arrays case in numarray instead of having to fight against a
jungle of Numeric/numarray/python array implementations. I strongly believe
that numarray has enough advantages over Numeric that would compensate the
effort to further enhance its present limitations rather than maintain
several packages.

Just my 2 cents,
