I don't know the answer to your question, but I have a related
question. I've read that subclasses Numeric and numarray is
non-trivial. Is this any easier with scipy core?
In more detail, I'd like to override + and * on arrays, but allow them
to be used in other ways as standard arrays, e.g. innerproduct(a,b)
should do the usual thing.
