  # This is an internal class for "dummy handler invocations" on sources
  # The problem is that invocations like source.namespace::name are
  # evaluated to (source.namespace).name 
  # This means that source.namespace must return an object on which
  # "name" can be called with the desired effect. This  object 
  # is the "dummy handler"
  class DummyHandler
    
    # Create the new handler
