Sounds cool. As far as I'm concerned, we ended up in agreement.

Alas, the real world kicks in. Unfortunately, there is just a ton of
syntactic scaffolding that should be built right into the smart pointer, and
that will end up being duplicated if distinct classes are to be written.

I guess the best common denominator, and one that will make both of us
entirely happy, is typedef templates.
