//> using scala "3.1.1"

// let's start with basic functor because all monads in scala have to be functors to work
// within a for-comprehension (because it desugars to flatMap + map chain)
// F[_] represents any concrete type parameterised with a single type (a type constructor), ie List, Option
trait Functor[F[_]]:
  def map[A, B](fa: F[A])(f: A => B): F[B]

// define a correct interface for a Monad that extends that Functor, Monad is just
// two functions: pure (return in hs) and flatMap (bind in hs)
