3. groupSort :: Ord k => [(k, v)] -> [(k, [v])]

   extra	Data.List.Extra

   A combination of group and sort.

   groupSort [(1,'t'),(3,'t'),(2,'e'),(2,'s')] == [(1,"t"),(2,"es"),(3,"t")]
   \xs -> map fst (groupSort xs) == sort (nub (map fst xs))
   \xs -> concatMap snd (groupSort xs) == map snd (sortOn fst xs)
   

4. groupSortBy :: (a -> a -> Ordering) -> [a] -> [[a]]

   extra	Data.List.Extra

   A combination of group and sort, using a predicate to compare on.

   groupSortBy (compare `on` length) ["test","of","sized","item"] == [["of"],["test","item"],["sized"]]
   

5. groupSortOn :: Ord b => (a -> b) -> [a] -> [[a]]

   extra	Data.List.Extra

   A combination of group and sort, using a part of the value to compare on.

   groupSortOn length ["test","of","sized","item"] == [["of"],["test","item"],["sized"]]
   

6. nubSort :: Ord a => [a] -> [a]

   extra	Data.List.Extra

   O(n log n). The nubSort function sorts and removes duplicate elements from a list. In particular, it keeps only the first occurrence of each element.

   nubSort "this is a test" == " aehist"
   \xs -> nubSort xs == nub (sort xs)
   

7. nubSortBy :: (a -> a -> Ordering) -> [a] -> [a]

   extra	Data.List.Extra

   A version of nubSort with a custom predicate.

   nubSortBy (compare `on` length) ["a","test","of","this"] == ["a","of","test"]
   

8. nubSortOn :: Ord b => (a -> b) -> [a] -> [a]

   extra	Data.List.Extra

   A version of nubSort which operates on a portion of the value.

   nubSortOn length ["a","test","of","this"] == ["a","of","test"]
   

9. groupSort :: Ord k => [(k, v)] -> [(k, [v])]

   extra	Extra

   A combination of group and sort.

   groupSort [(1,'t'),(3,'t'),(2,'e'),(2,'s')] == [(1,"t"),(2,"es"),(3,"t")]
   \xs -> map fst (groupSort xs) == sort (nub (map fst xs))
   \xs -> concatMap snd (groupSort xs) == map snd (sortOn fst xs)
   

10. groupSortBy :: (a -> a -> Ordering) -> [a] -> [[a]]

    extra	Extra

    A combination of group and sort, using a predicate to compare on.

    groupSortBy (compare `on` length) ["test","of","sized","item"] == [["of"],["test","item"],["sized"]]
