BindRec

Companion object BindRec

trait BindRec[F[_]] extends Bind[F]

scalaz.Bind capable of using constant stack space when doing recursive binds.

Implementations of tailrecM should not make recursive calls without the @tailrec annotation.

Based on Phil Freeman's work on stack safety in PureScript, described in Stack Safety for Free.

def ap[A, B](fa: ⇒ F[A])(f: ⇒ F[(A) ⇒ B]): F[B]
Sequence f, then fa, combining their results by function application.
Sequence f, then fa, combining their results by function application.
NB: with respect to apply2 and all other combinators, as well as scalaz.Bind, the f action appears to the *left*. So f should be the "first" F-action to perform. This is in accordance with all other implementations of this typeclass in common use, which are "function first".
