I was actually asking about replacements for valarray, not NumPy. In any
case, I doubt that Blitz++ would wrap well, since its primary feature is
template metaprogramming. As a matter of fact, some people have been using
"runtime expression templates" in the Python world, but I don't think you
could base this on Blitz++ because in Blitz++ the expression trees are all
computed at compile time.
