Yes, it does. That's where I heard about it. That also brings up a good
point. Paul mentioned that using something like Blitz++ would only help
performance if you could pass it an entire expression, like: x =
a+b+c+d. That is exactly what Eric's compiler module does, and it would
sure be easier if NumPy already used Blitz++! In Fact, I suppose Eric's
compiler is a start towards a tool that could comp9le en entire NumPy
function or module. I'd love to be able to just do that (with some
tweeking perhaps) rather than having to code it all by hand.

My fantasies continue...
