There is Quasar if you want Go or Erlang style concurrency in either Java or Kotlin (and the Pulsar wrapper to it for Clojure).

No reason to bake it into the language -- and as you can see from comparing the Java and Kotlin sample code, there is a reason for a language that let you write Groovy-like DSLs.

Go-style channels and goroutines are built on green threads which Go/Erlang has, but the JVM does not have. One way to work around this is to use fibers and continuations which is what Quasar is doing.
