One more quick thing; Looking at the gnat implementation they
do the following:

               --  Read the internal tag (RM 13.13.2(34)) and use it to
               --  initialize a dummy object with the right tag value:

               --    Dnn : root_type;
               --    Dnn._tag := Internal_Tag (String'Input (Strm))

               --  This dummy object is not initialized (other than its tag)
               --  and is used only to provide a controlling argument for the
               --  eventual _Input call.

Unfortunately this is hidden from me..  Am I trying to do something
that is even too dynamic for the new Ada? Without this capability
I cannot overload the 'Class'Input operations without a Case statement..
