It did eliminate one thing, the need to have a scheme to create an object of 
each tagged type. That forced the use of either a case statement or an 
access-to-subprogram, either of which is error-prone.

There is no possibility of eliminating the need for some sort of registry --  
although in some cases you can use the one built-into the language (the 
External_Tag). There has to be a mapping somewhere of some sort of key to a 
tag, since it isn't possible to export tags to the "real world".
