I've noticed that clojure.lang.Namespace cannot be used with the name-
function (like (name *ns*)) because it does not implement
clojure.lang.Named. One has to use (.getName *ns*), which is a bit
ugly.

        user=> (show clojure.lang.Named)
        ===  public abstract interface clojure.lang.Named  ===
        [ 0] getName : String ()
        [ 1] getNamespace : String ()
        nil



In contrast, the name of a namespace is a symbol:

        user=> (class (.getName *ns*))
        clojure.lang.Symbol



As Meikel mentioned, Clojure provides ns-name for this purpose.

I've had this same thought in the past, but the Named interface returns strings from its .getName and .getNamespace calls: Subclasses of Named are named by either one string (when not namespace qualified) or by two strings (when namespace qualified). Given that difference, it would not be appropriate for clojure.lang.Namespace to implement clojure.lang.Named.
