  4. def analyze[M](f: ~>[F, [α]M])(implicit arg0: Monoid[M]): M

    Performs a monoidal analysis over this free program.

    Performs a monoidal analysis over this free program. Maps the effects in F to values in the monoid M, discarding the values of those effects. Example:

    def count[F[_],B](p: FreeAp[F,B]): Int =
  p.analyze(new (F ~> λ[α => Int]) {
    def apply[A](a: F[A]) = 1
  })
