Also, functions called on things of type matrix may not return a  
matrix as expected, but rather an array.

Anecdotally, it seems to me that lots of people (myself included) seem  
to go through a phase early in their use of NumPy where they try to  
use matrix(), but most seem to end up switching to using 2D arrays for  
all the aforementioned reasons.
