FWIW, I still believe that a language-based solution is best. ZUTO is a hack
that takes the Colvin/Gibbons trick (used in auto_ptr) to new, rarefied
heights.

But realistically, a language change is likely to be in effect in 3 years in
theory, and in 5-7 for practical purposes. So I am very happy that now we
have a solid solution within the current language.
