As far as I can tell from the wording of N3649, perfect forwarding is not
currently possible via generic lambdas, as the invented type
template-parameter names are not accessible:

    // utterly contrived example
    template< class T >
    auto make_factory() // using N3638 return type deduction
    {
        return []( auto&&... args ) {
            return std::unique_ptr<T>( new T( std::forward<???>(args)... ));
        }
    }

Am I correct in this conclusion?
If so I'm guessing this wasn't merely an oversight, and is the reason just
practicality of exposing the invented parameter names?

TIA -- Rob
