Rich, Very helpful, as always. Alias + the ability to pull in symbols names via refer was exactly what I was looking for.
One scenario still worries me: 1. I create a multimethod that dispatches around a tag whose value is an unresolved keyword (:Foo instead of ::Foo). Everything works fine. 2. If at some later point I want the dispatch to depend on (derive), it is breaking change for clients to switch to from :Foo to ::Foo. I am tempted to conclude that you should never use unqualified keywords as type tags, because you are exposing an implementation detail. That is, the implementation promises not to rely on derive.
