Depends on the mechanism. If it is supposed to be user-extensible
(i.e. an open set) then strings are bad because there might be clashes
between extensions made by separate libraries. With constants (or
unique names) as denotations no such issue exists.

IOW, strings don't scale well. They are only suitable for closed sets.
