Apart from being blasphemous - would it be a good idea to override clojure.lang.Ref in Java land?
I want to create (children of?) refs in clojure that send an agent when they change, so that I can create facilities to observe changes to them. Creating a 'MyRef extends Ref' seems to be the obvious Java way. Don't know whether the #^clojure.lang.Ref tags in the clojure ref functions would cause problems, though (is it like instanceof or is it a (arg.getClass() == ... comparison?). This might be the easiest way for a Java developer, but shouldn't it be possible to develop this in Clojure land in an easy manner?
