I guess I will wait and see. The worry I have is that when people attempt
to use a PyMatrix where a numarray is expected (and the same issue
would be true for Numeric) that the behavior of expressions may 
cause some confusion (i.e., since matrix multiplies may happen
instead of element-wise operations). This most likely will result in
some visible exception (e.g., incompatible shapes) but may not.
If people never mix the two, it won't be a problem; or if they are
careful to convert before doing so.
