trait Monad[M[_]] extends Applicative[M]

Simple implementation of a Monad type-class. Subclasses only need to override apply and flatMap, but they should override map, join, joinWith, and sequence if there are better implementations.

Laws Monads must follow: identities: flatMap(apply(x))(fn) == fn(x) flatMap(m)(apply _) == m associativity on flatMap (you can either flatMap f first, or f to g: flatMap(flatMap(m)(f))(g) == flatMap(m) { x => flatMap(f(x))(g) }
