As long as we are on about this sort of stuff, do you recall what the
reason was for using the "record" syntax with tagged types?  Again,
not a big deal, but it seems kinda odd.  Why not simply:

    type T is tagged
        ...
    end T;

    type C is new T with
        ...
    end C;

    type D is new T with null;

Why the "record" syntax.  Especially since tagged types are more
different from records than similar (extensible, dispatchable
primitive ops, maintain composability of user defined equal, ...)
