Clojure is great. Brining together Lisp with the Java ecosystem makeand its concurrency model makes it great for building backend system, while still enabling quick changes. One thing that I found noteworthy is that Clujure did not pickup some innovations happening at Java since like version 8, such as Invoke Dynamic in the JVM or streams.

Generally for streams, the equivalent in Clojure with sequences or transducers is much cleaner and simpler so there was not a lot of reason to want them from Clojure. However, it is important to provide interop paths to work with Java libs that make use of them.

The functional interface coercion is implemented with invokedynamic.
