You could add a direction flag +/-1 which doesn't get printed. When comparing they should compare taking the direction into account so x < y == y > x. lhs and rhs...not sure here. I guess I would return the actual slots 0 and 1 and add another property that gives direction (the +/-1) and a method to make it canonical...but perhaps that could be done with simplify so that all directions end up being positive?
