Perhaps we've already got an interface, it just isn't used...

If every method was dispatched via Object#send, then we could hook it
at all levels.

  class Object
    alias :oldSend :send
    def send(msg, *args)    # doesn't currently work
      preAdvice
      oldSend(msg, *args)
      postAdvice
    end
  end
