What do you think about using the templated constructor *and* SFINAE out via enable_if the binding of U to initialized<T> (or, maybe, to any class derived from initialized<T>)?
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>.
Here is an example that fails to compile on MSVC because of the compiler bug. Please let me know if you can fix it by SFINAE. (But I'm afraid it won't work.)
I'm not sure if I missed something, but this seems to work
template<class U> explicit initialized(const U& arg, typename boost::disable_if<boost::is_base_and_derived<initialized, U> >::type* = 0)
That's what I had in mind. Although, echoing Steven: Maybe we should just settle for the dead plain simple initialized(const T&) constructor. - Jeff
