Note that this would make it slightly easier to pass a custom sort
function that forced everything to be totally ordered[*], but followed
the standard ordering when one was available.

[*]  yes, it would be possible to trick this function with so that the
end result for a full sequence depended on the order of comparisons.
But that is already true with custom comparisons.
