Java objects are passed to Clojure functions in exactly the same way they are passed to Java method (because internally Clojure function is just an implementation of IFn interface, and function call is invoke(...) on its instance). But I don't want to pass services to Clojure functions, I'd like to inject them into Clojure namespace when clojure.core/require is executed. By itself, clojure.core/require doesn't allow passing arbitrary arguments that might be used later inside the namespace. So I'm not yet sure about correct way to approach this.
