I remember that thread clearly, as I think making it easy to write new 
Ufuncs (and others) that perform at C speed could make a real difference 
to how effective SciPy ultimately is. I say SciPy, because I believe a 
large collection of special purpose optimized functions probably doesn't 
belong in in Numarray itself.

Yes, I remember that answer, and was disappointed, though the logic of 
not-re-implkimenting C++ templates is pretty obvious. Which brings up 
the obvious question: why not use C++ templates themselves? which is 
what Blitz does. This points ot weave.blitz at the obvious way to write 
optimized special purpose functions for SciPy. Does weave.Blitz work 
with Numarray yet?

Clearly it's time for me to check it out more...

allowing Pyrex to use templates would be great.. but how would that be 
better than weave.blitz? Or maybe Pyrex could use blitz.

I'm kind of over my head here, but I hope something comes of this.
