countable: Countable, Searchable, Finite, Empty classes.
class Countable, for countable types class AtLeastOneCountable, for countable types that have at least one value class InfiniteCountable, for infinite countable types class Searchable, for types that can be searched over class Finite, for finite types class Empty, for empty types data Nothing, an empty type
Also includes these orphan instances:
instance (Searchable a,Eq b) => Eq (a -> b) instance (Finite a) => Foldable ((->) a) instance (Finite a) => Traversable ((->) a) instance (Show a,Finite a,Show b) => Show (a -> b)
Could you put these instances in a dedicated module? In the same vein I would like to have a newtype wrapper over functions were intention is to be used extensionally. Nice package BTW! -- Nicolas Pouillard http://nicolaspouillard.fr
