That *still* won't make streams compatable between diferent compilers
though, will it? Isn't the representation of a tagged type's tag on
'output implementation defined? You can of course specify it. But you'd
have to know ahead of time that you want to use streams portably with
your objects, then go in and specify the external tag for every object.
