sort : ('a -> 'a -> bool) -> 'a list -> 'a list
STRUCTURE
SYNOPSIS
Sorts a list using a given transitive ‘ordering’ relation.
DESCRIPTION
The call sort opr list where opr is a curried transitive relation on the elements of list, will sort the list, i.e., will permute list such that if x opr y but not y opr x then x will occur to the left of y in the sorted list. In particular if opr is a total order, the result list will be sorted in the usual sense of the word.
FAILURE
Never fails.
EXAMPLE
A simple example is:
   - sort (curry (op<)) [3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5, 8, 9, 7, 9];
   > val it = [1, 1, 2, 3, 3, 4, 5, 5, 5, 6, 7, 8, 9, 9, 9] : int list
The following example is a little more complicated. Note that the ‘ordering’ is not antisymmetric.
   - sort (curry (op< o (fst ## fst)))
          [(1,3), (7,11), (3,2), (3,4), (7,2), (5,1)];
   > val it = [(1,3), (3,4), (3,2), (5,1), (7,2), (7,11)] : (int * int) list

COMMENTS
The Standard ML Basis Library also provides implementations of sorting.
