Clojure has been out now for nearly 5 years. I don't expect to see many new language features moving forward. And we can agree to disagree about those features not belonging in user-land. Additions to the core lib are the kinds of things users will demand in all good Clojure implementations - JVM or JS. That said, two big language things you might see in the future depending on how much effort gets put into them - Pods & Predicate Dispatch.
