Well, I guess I have to believe in you provided that I'm not an expert
on these issues and you are. However, I think Todd Miller has some
hopes that Numarray can eventually get rid of this object creation
latency. That would be very nice as well.

In any case, and as a person already said before during the message
storm that took place in this distribution list this weekend, I was
rather sceptical when you first announced the project for Numeric 3.0.
But now, and after reading this bunch of messages, I've changed my
mind and think (hope) that your approach can be very beneficial for
unifying the Numeric and numarray split.

I whish you the best of luck in your attempt, and I'll keep an eye on
Numeric 3.0 evolution. It would be wonderful if you finally succeed,
and we can finally have a standard numerical package for Python,
irregardless it will be in the Standard Library or not.

Cheers!,
