Imperfect as my proposal is I think that OP Eli would find it an 
improvement over today's behavior.  The current mechanism does not handle 
tags with divergent definitions.  Worse, even after a tag has been killed 
it comes back.  Eli did not ask to be able to move / redefine a tag.  He 
simply did not want it to behave as a zombie, repeatedly coming back from 
the dead.
