  7. def iterateForeverM[F[_], B](f: (A) ⇒ F[A])(implicit F: FlatMap[F]): F[B]

    iterateForeverM is almost exclusively useful for effect types.

    iterateForeverM is almost exclusively useful for effect types. For instance, A may be some state, we may take the current state, run some effect to get a new state and repeat.

  8. def tailRecM[F[_], B](f: (A) ⇒ F[Either[A, B]])(implicit F: FlatMap[F]): F[B]

    Example:

    Example:

    scala> import cats.implicits._
    
    scala> val a: Int = 10
    scala> a.tailRecM[Option,String](i => if (i == 20) Some(Right("done")) else Some(Left(i+1)))
    res0: Option[String] = Some(done)
