I found some missing instances in the base package. The instances below are almost unique by parametricity.
Data.Complex: instance Functor Complex instance Applicative Complex instance Foldable Complex -- real first instance Traversable Complex
Data.Functor.Identity: instance Monoid a => Monoid (Identity a)
Control.Applicative: instance Foldable ZipList instance Traversable ZipList
I'm going to write a patch if there is no issue with them.
Also, I wonder if () could be Storable:
instance Storable () where sizeOf _ = 0 alignment _ = 1 peek _ = return () poke _ _ = return ()
