Yes, of course.

Double is an excellent example since it indicates that there exist types 
for which Ord (and Eq) instances are not quite sensible, but nonetheless 
we want them to exist because it is a real pain if they don't. (Or at 
least, we definitely want Ord. It's easier make the argument that we 
don't really want Eq)
