In haskell contravariant we can find a new operator >*< which is an alias for divided. It allows us to nicely capture duality of Divide and Apply - we can write:

nonNegative = Predicate (_ >= 0)

q = (_.x &&& _.y &&& _.z) >$< nonNegative >*< nonNegative >*< nonNegative

Should I provide a PR with such addition to the library?
