Can't figure out how to implement an interface in Clojure CLR

implement-interface.clj

; This does not work, boo! Don't know how to tell Clojure that IsReusable is a property

(System.Reflection.Assembly/LoadWithPartialName "System.Web")

(defn foo-handler []
	(reify System.Web.IHttpHandler
		(IsReusable [] false)
		(ProcessRequest [context] ())))

I haven't found much on Google for examples on implementing interfaces. I did find this one which is an example for Clojure JVM:

http://mylesmegyesi.blogspot.com/2011/12/implementing-java-interfaces-in-clojure.html

This seems to work, at least the compiler doesn't complain:

user=> (def foo-handler
    (reify System.Web.IHttpHandler
            (get_IsReusable [this] false)
            (ProcessRequest [this context] ())))
#'user/foo-handler
user=> (instance? System.Web.IHttpHandler foo-handler)
true
user=>

This is better and works fine in an ASP.NET app:

(deftype foo-handler []
    System.Web.IHttpHandler
    (get_IsReusable [this] false)
    (ProcessRequest [this context] 
        (.Write (.Response context) "Hello, From Clojure CLR!")))
