This is an assumption that I never quite understood. What most people
want is to have sorted data, they don't care if I used a sorting or
non-sorting comparison to do it. I think it is just that in most cases
n is not very big anyway and comparison sorts make it easier on the
programmer to create arbitrary types that are sortable.
