:: Ord a => [a] -> [a] package:Cabal

The sort function implements a stable sorting algorithm. It is a special case of sortBy, which allows the programmer to supply their own comparison function. Elements are arranged from from lowest to highest, keeping duplicates in the order they appeared in the input.
>>> sort [1,6,4,3,2,5]
[1,2,3,4,5,6]
Like nub, but has O(n log n) complexity instead of O(n^2). Code for ordNub and listUnion taken from Niklas Hambüchen's ordnub package.
A right-biased version of ordNub. Example:
>>> ordNub [1,2,1] :: [Int]
[1,2]
>>> ordNubRight [1,2,1] :: [Int]
[2,1]
