Category:         Data
Synopsis:         List-like structures with static restrictions on the number of elements
Description:
  We provide the data type @NonEmpty@ that allows to store a list-like structure
  with at least or exactly @n@ elements,
  where @n@ is fixed in the type in a kind of Peano encoding
  and is usually small.
  The datatype is intended to increase safety
  by making functions total that are partial on plain lists.
  E.g. on a non-empty list, 'head' and 'tail' are always defined.
  .
  There are more such data types like @Optional@ and @Empty@.
  Together with @NonEmpty@ you can define a list type
  for every finite set of admissible list lengths.
  .
  The datatype can be combined with Lists, Sequences and Sets
  (from the @containers@ package).
  .
  The package needs only Haskell 98.
  .
  Similar packages:
  .
  * @semigroups@, @semigroupoids@:
    restricted to lists, minimum number of elements: 1,
    provides more type classes tailored to the use of non-empty lists.
  .
  * @NonEmptyList@:
    restricted to lists, minimum number of elements: 1
  .
  * @NonEmpty@:
    restricted to lists, minimum number of elements: 1,
    designed for unqualified use of identifiers
  .
  * @Cardinality@:@NeverEmptyList@
  .
  * @mono-traversable@:@Data.MinLen@:
    allows to specify a minimum number of elements using type families
    and works also for monomorphic data structures like 'ByteString'
  .

  Related packages:
  .
  * @Stream@:
    Lists that contain always infinitely many elements.
  .
  * @fixed-length@:
    Uses the data structure of this package
    and defines a closed-world class for fixed-length lists
    and an according index type.
  .
  * @fixed-list@:
    Uses the same data structure as this package
    but is intended for fixing the number of elements in a list.
    Requires multi-parameter type classes with functional dependencies.
