It is implementing Clojure which does not have static typing so my strong assumption would be no

Clojure offers static typing as a library.

Is that 'core.typed' ?

Does it introduce incompatibilities with third-party libraries?

		typed Clojure has both Clojure and ClojureScript implementations, so it's not tied to the JVM https://github.com/typedclojure/typedclojure
