earlier quicksort. For very small lists this may result in slightly
slower sorting times, but in general the speedup should be at least 20%.
Additional bonuses are that the worst case behaviour of sort() is now
-better (in computer science terms it is now O(N log N), as opposed to
-O(N**2) of quicksort), and that sort() is now stable (meaning that
-elements with identical keys will stay ordered as they were before
-the sort).
