Yes, you are right. > This happens for the same reason that your patch is needed in the first > place: we're eagerly substituting a constant. Absolutely, that's the point. On the other hand, it is very important to emphasize that we cannot solve this problem with a stronger solver, see my example with 3 variables and two equations above. Also, another interesting question is (drawn up by @steakhal) if we can/could handle associativity somehow. Commutativity seems to be handled by the constraint manager (alas we'd search for "y + x" when we query "x + y").
