Sorry for the late reply.   I will definitely consider submitting a pull
request to numexpr if it's the direction I decide to go.  Right now I'm
still evaluating all of the many options for my project.

I am implementing a machine learning algorithm as part of my thesis work.
I'm in the "make it work", but quickly approaching the "make it fast" part.

With research, you usually want to iterate quickly, and so whatever
solution I choose has to be automated.  I can't be coding things in an
intuitive, natural way, and then porting it to a different implementation
to make it fast.  What I want is for that conversion to be automated.  I'm
still evaluating how to best achieve that.
