GOOPS[0] in guile is definitely hugely inspired by CLOS, which also has generic functions with multi-method dispatch.

I highly recommend guile to anyone who wants the battery included nature of common lisp. I know that racket is also a great choice here, I just have little experience with it.

Racket's object system is largely inspired by Java. So is its statically-compiled module system (in which you can't change anything once it's been compiled, unlike a real Lisp), and Raco build tool. Programming with objects in Racket feels a lot like programming with Java objects in Clojure.
