def and[H[_]](h: FunctionK[F, H]): FunctionK[F, [γ$4$]Tuple2K[G, H, γ$4$]]

Composes two instances of FunctionK into a new FunctionK that transforms one single functor to a cats.data.Tuple2K of two functors.

scala> import cats.arrow.FunctionK
scala> val list2option = λ[FunctionK[List, Option]](_.headOption)
scala> val list2vector = λ[FunctionK[List, Vector]](_.toVector)
scala> val optionAndVector = list2option and list2vector
scala> optionAndVector(List(1,2,3))
res0: cats.data.Tuple2K[Option,Vector,Int] = Tuple2K(Some(1),Vector(1, 2, 3))

def andThen[H[_]](f: FunctionK[G, H]): FunctionK[F, H]

Composes two instances of FunctionK into a new FunctionK with this transformation applied first.
