The strings I'm working with are ISO formatted dates, and one of the reasons many people like to use ISO formatted dates is that they sort easily. However, the specifics of the situation are really irrelevant.
I just thought it might be seen as incongruent that Clojure has an elegant collection system based on the Collections interfaces, and have max and min functions that only operate on numbers. It would seem we should embrace the Comparable and Comparator interfaces as well.
