:: Ord a => [a] -> [a] -package:witherable -package:Cabal-syntax -package:ghc -package:base -package:containers -package:basement package:Cabal

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]
A total variant of tail.
A total variant of init.
