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
