So how hard it would it be right now, for example, to implement in Clojure a deftype that responds to all the functions a sorted map responds to? I started looking through the source code to try to figure out what interfaces I'd need to override, but it seemed like an overwhelming mixture of Clojure and Java interfaces, and very difficult to get right without the ability to use the existing abstract base classes that are in place (AFn, ASeq, APersistentMap, etc.). For example, it seems like to implement IFn, you'd need to manually write out cases for the first twenty arities. Would you recommend waiting until the core abstractions are re-architected before tackling something like this, or is there an easy way to do this I'm not seeing?
