You can get a pretty long way but there are still things that need to be improved over time. For example Clojure still 7 years after the java 8 release doesn't have great integration with java 8 functional interfaces, which is a pretty big detriment to java interop. I saw this patch which seems to have been submitted by a community member https://clojure.atlassian.net/browse/CLJ-2637 (not sure if the author is a core contributor or what), but even after month no comment from Rich or anyone else on the team to indicate if this is a good idea, if they'd let it in or what.
