CpsEffectMonad

cps.CpsEffectMonad
trait CpsEffectMonad[F[_]] extends CpsMonad[F]

Marker trait, which mark effect monad, where actual evaluation of expression happens after building a monad, during effect evaluation stage.

Concrete methods

def delay[T](x: => T): F[T]

For effect monads it is usually the same, as pure, but unlike pure, argument of evaluation is lazy.

For effect monads it is usually the same, as pure, but unlike pure, argument of evaluation is lazy.

Note, that delay is close to original return in haskell with lazy evaluation semantics. So, for effect monads, representing pure as eager function is a simplification of semantics, real binding to monads in math sence, should be with delay instead pure
