And there was this c-vs-c comment from (IIRC) axman on the #ghc IRC channel:

> class Category (c :: k -> k -> *) where
>   type Ob c :: k -> Constraint
>   id :: Ob c a => c a a
>   (.) :: (Ob c a, Ob c b, Ob c c) => c b c -> c a b -> c a c

This is pretty confusing for anybody whose brain does not yet
instantly 'autocorrect' these kinds of mistakes.

Cheers,
