For me it doesn't. You cannot prevent user from shooting his foot in
this case. For example consider:
let cmp x y = Random.int ()
This is very good comparision functions, and can also be used with
functiorial interface. You may say it is silly, but random functions
(that are not total orderings) can be created by accident (for example
by comparing some mutable member or what's not).
