I really hope this isn't true, Clojure is my favorite programming language. I feel that it spoiled me. Builds are easy, code is elegant and easy to parse, functional programming combined with immutable data structures is beautiful. It also is great for "full-stack" devs in that there is little context switching between server and client.

I think the "killer app" that Clojure needs is that it should be compilable into C/C++ with the same great interop it has with Java. It would be amazing to be able to utilize all those libraries, all those frameworks, all that code... in a Clojure REPL!
