Concrete methods
Summon an instance of Applicative for F.
Creates an applicative functor for F, holding domain fixed and combining
over the codomain.
Creates an applicative functor for F, holding domain fixed and combining
over the codomain.
Example:
scala> import cats.implicits._
scala> import cats.Applicative.catsApplicativeForArrow
scala> val toLong: Int => Long = _.toLong
scala> val double: Int => Int = 2*_
scala> val f: Int => (Long, Int) = catsApplicativeForArrow[Function1, Int].product(toLong, double)
scala> f(3)
res0: (Long, Int) = (3,6)
