This packages defines a list data type with statically known length by nesting the NonEmpty and Empty data structure from the non-empty package. We provide a closed world class for this class of structures http://www.haskell.org/haskellwiki/Closed_world_instances and a wrapper that makes all these lists Traversable and Applicative with ZipList semantics.
