12003,"Implement is_constrructible<T, U> -- no variadics",akrzemi1,John Maddock,"In the current implementation of trait boost::is_constructible, unless the compiler offers variadic templates (and some more), is implemented as boost::is_convertible, and that's it.

I understand the limitations, but would it be possible to provide a more accurate version for the case with exactly two parameters: boost::is_constructible<T, U>. This would check the construction with a single argument, so it does not require variadic templates, and it would cover a significant number of use cases. For instance it would unblock my ticket:
