4. implicit def ApplyFold[M[_], T](implicit arg0: Monad[M]): Apply[[γ$0$]Fold[M, T, γ$0$]]

   

   Apply instance

   Apply instance

   This means that we can write:

   val mean: Fold[Int, Int] = (sum |@| count)(_ / _)

   An Apply instance is also a Functor instance so we can write:

   val meanTimes2 = mean.map(_ * 2)

6. implicit def ComposeFold[M[_]](implicit arg0: Monad[M]): Compose[[β$6$, γ$7$]Fold[M, β$6$, γ$7$]]

   

   A Fold can be turned into a Compose

   A Fold can be turned into a Compose

   This allows us to write:

   val scans = sum compose list

11. implicit def ProfunctorFold[M[_]](implicit arg0: Monad[M]): Profunctor[[β$2$, γ$3$]Fold[M, β$2$, γ$3$]]

    

    Profunctor instance

    Profunctor instance

    This is especially useful because we can "map" on the input element

    val doubleSum = fromMonoid[Double] // sum all elements val roundedDoubleSum = doubleSum.mapfst(_.round)
