SFINAE/enable_if might be interesting indeed, but I'm not sure if it's really necessary. And I don't think it will help to work around the specific MSVC bug <http://connect.microsoft.com/VisualStudio/feedback/details/423737>.

Yes it does! Thanks, Steven. Sorry, I was wrong, thinking that it wouldn't work! Still I'd rather postpone adding a templated initialized(const U&) constructor until we have a user request and/or a motivating use case. For the time being I think a non-templated initialized(const T&) constructor should be sufficient, for the new boost::initialized<T>.
