It would be better if it weren't there. One way to obtain this would be to use constants that, at a given level in an expression subtree, were numbered the same, so you might have C1*(C2*x + C2*y) + C1*(C2/x + C2/y). So if the renumbering did that for testing purposes, the doctests and tests would pass. -- You received this message because you are subscribed to the Google Groups "sympy" group.
