  7. def const[F[_], C](c: C)(implicit arg0: Applicative[F]): WithContext[F, C]

    Creates constant Context of type C in F

    Creates constant Context of type C in F

    Allows to put some value into context of F even when F itself does not have any way to store it

    Example: 

    1.  case class MyCtx(id: Int)

val program: Option[String] = { implicit val ctx = Context.const[Option, MyCtx](MyCtx(3))

Context[Option].ask(ctx => ctx.id.toString) }
