and in the case of String, this happens:
https://github.com/clojure/clojure/blob/master/src/jvm/clojure/lang/RT.java#L547
else if(o instanceof CharSequence)
return ((CharSequence) o).length();
=> (dorun (map println (supers (class "a string here"))))
java.lang.Object
java.lang.Comparable
java.io.Serializable
java.lang.*CharSequence*
nil
