# The countable package

`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)`
