Comment (by guest):
The problem with using uniqIds is that the order used when a module is
compiled must be the same as the order used when it is imported. Do the
existing uniqIds have that property?
The suggestion to restrict this to a special type-class is a good one.
Maybe this should be done as a special kind of `deriving`. I would prefer
a new class to an extension of an existing one.
