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)@ / /
