Alan, I have thought about this a little too. I have not had time to work on it recently. The issue I ran into is that to make this work well in SymPy you really need the concept of an infinitesimal dx, dy, dz, etc. Things got circular when I tried to implement that using the sympy definition of functions. It might be worth comparing notes. I would really like to be able to work with total differentials and do integrations on expressions containing infinitesimals in the Leibniz style notation.
