Yes, Julian is doing an amazing work on getting rid of temporaries inside
NumPy.  However, NumExpr still has the advantage of using multi-threading
right out of the box, as well as integration with Intel VML.  Hopefully
these features will eventually arrive to NumPy, but meanwhile there is
still value in pushing NumExpr.
