yeah - it's quite strange.  unfortunately the 'send' approach won't work
because the actual usage is something like

   class Controller
     def method
       handler = Handler::new self
       handler.encode '42'
     end
   end

   class Handler
     def initialize controller
       @controller = controller
     end
     def encode msg
       @controller.instance_eval do
         #
         # many things which need to be insider the controller
         #
       end
     end
   end

that 'private' methods __are__ allowed is really strange indeed.
