Note that this is not subsumed by Signal.applicativeInstance because Signal.applicativeInstance requires a Concurrent[F] since it non-deterministically zips elements together while our Functor instance has no other constraints.

Note that this is not subsumed by Signal.applicativeInstance because Signal.applicativeInstance requires a Concurrent[F] since it non-deterministically zips elements together while our Functor instance has no other constraints.

Separating the two instances allows us to make the Functor instance more general.

We put this in a SignalLowPriorityImplicits trait to resolve ambiguous implicits if the Signal.applicativeInstance is applicable, allowing the Applicative instance to be chosen.
