Re: [Boost-Users] Any use of a Singleton<> template

Can you compare/contrast your library to SingletonHolder<> in the Loki
library as described by Andrei Alexandrescue in "Modern C++ Design?"

I would guess that Andrei's singleton is probably the most familiar to
people on this list and I suspect that if he survives the slings and arrows
of submitting his smart pointer he will offer this as well.
