If something is a "major nuisance" to do, then you should interpret that
to mean that you shouldn't be doing it.

Do not try to send a tagged type directly across an external interface.
You must first convert the object to an external format, preferably
using the streams facility and/or the DSA.

No good answers, becuase the question itself is all wrong.

Please don't fight the language, as there are "standard and portable"
ways to get the job done.  That the representation of a tagged type
isn't under programmer control is a feature, not a flaw.
