I gave it a look. The technique is remarkable, and IMHO useful when a
discriminated union is needed/opportune by design.

But in the example I was thinking of (a generic buffer<T>) the union
would be there as an "optimization" only. That stuff + the
double-buffer technique gives quite a raise to code complexity with an
overall "benefit" which is really difficult to measure (besides being
presumably variable among implementations).

And then, I was thinking to an aid for dynamic_bitset where T is a
built-in type so who cares about exceptions? :-) Well, just kidding!
However I think that's not worth the pain. Any other opinions?

Genny.
