Maybe. Odds are if you write a rule that returns the wrong one everything will just work fine. We provide both to allow for clearer writing of rules, and easier debugging. -`Zero()` represents the fact that if one perturbs (adds a small change to) the matching primal there will be no change in the behavour of the primal function. +`Zero()` represents the fact that if one perturbs (adds a small change to) the matching primal there will be no change in the behaviour of the primal function. For example in `fst(x,y) = x`, then the derivative of `fst` with respect to `y` is `Zero()`. `fst(10, 5) == 10` and if we add `0.1` to `5` we still get `fst(10, 5.1)=10`.
