description:
    * @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. This turns out to include some infinite types, see <http://math.andrej.com/2007/09/28/seemingly-impossible-functional-programs/>.
    .
    * @class Finite@, for finite types
    .
    * @class Empty@, for empty types
    .
    * @data Nothing@, an empty type
    .
    Some orphan instances:
    .
    * @(Searchable a,Eq b) => Eq (a -> b)@ / /
    .
    * @(Finite t) => Foldable ((->) t)@ / /
    .
    * @(Finite a) => Traversable ((->) a)@ / /
    .
    * @(Show a,Finite a,Show b) => Show (a -> b)@ / /
