class StaticApply m => StaticBind m where

Instances of StaticBind should satisfy the following laws (writing staticMap, staticApply, staticBind as infix (<$>), (<*>), (>>=), respectively):

(m >>= f) >>= g = m >>= static (.) `cap` (staticFlippedBind g) cap f
staticJoin . staticJoin = staticJoin . staticMap (static staticJoin)

where

staticFlippedBind :: Closure (b -> m c) -> Closure (m b -> m c)
staticFlippedBind = capDup (static (flip staticBind))
