-  # So when an object calls a method, or sends a message, this is what it sends: a Message
-
-  # A message contains the sender, return and exceptional return addresses,the arguments,
-  #  and a slot for the named_list.
-
-  # As such it is a very run-time object, deep in the machinery as it were, and does not have
-  # meaningful methods you could call at compile time.
-
-  # The methods that are there, are nevertheless meant to be called at compile time and generate
-  # code, rather than executing it.
-
-  # The caller creates the Message and passes control to the receiver's method
-
-  # The receiver create a new NamedList to hold local and temporary variables and (later) creates
-  # default values for arguments that were not passed
-
-  # How the actual finding of the method takes place (acording to the ruby rules) is not simple,
-  # but as there is a guaranteed result (be it method_missing) it does not matter to the passing
-  #  mechanism described
-
-  # During compilation Message and named_list objects are created to do type analysis
