This is similar, but not identical, to the idea behind the DeferredVector patch I made a few weeks back but haven't had time to tend to. I wonder if the ideas could share some mutual implementation. See http://code.google.com/p/sympy/issues/detail?id=1268 for more info on the DeferredVector approach I took. -Andrew --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy" group.
