Sorting

sortKeys :: forall l a b. (AssocList l a b, Ord a) => l -> l

Sort an association list according by its keys. This is a stable sort, so when a key appears multiple times in the input list, the ordering of its values in the resulting list remains unchanged.

>>> sortKeys [(2, 'b'), (3, 'c'), (2, 'a'), (4, 'd'), (2, 'e'), (1, 'f')]
[(1,'f'),(2,'b'),(2,'a'),(2,'e'),(3,'c'),(4,'d')]
