For example, given a Java class like:

public class Foo {
  public String bar(String x) {
    return "string " + x;
  }
  public String bar(Integer x) {
    return "integer " + x;
  }
}

How can I subclass Foo in Clojure and override only the bar(String) method but reuse the bar(Integer) from the original Foo class. Something like this (but this won't work):

(let [myFoo (proxy [Foo] [] 
              (bar [^String x] (str "my " x)))]
  (println "with string:  " (.bar myFoo "abc"))
  (println "with integer: " (.bar myFoo 10)))

This example will print:

with string:   my abc 
with integer:  my 10

but I would like to get the effect of:

with string:   my abc 
with integer:  integer 10
java proxy clojure
