Sit two theoretically identical programmers who have a decent grasp of
python, understand the basics of ElementwiseProxy and the components
of your version down side by side, and see which one can figure out
what the output should be first.  I will bet real money it is the one
working with the ElementwiseProxy code.  We have all had a lot of
practice reading inside out and backwards in the python community with
comprehensions and such, but it is in no way natural or easy.

Additionally, everything done via an ElementwiseProxy is lazy, so you
only pay for what you eat :)
