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".
