    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".
