What about the fact that Numpy accommodates Python's dynamic typing?  You can pass arrays of integers, floats, bytes, or even PyObjects.  I don't know exactly how all that is implemented.  

In my case, I was always passing floats.  So what I assumed that psyco was doing for me was compiling a neural network class that always expected floats.
