I'd like to see a feature-test for LWG2296, "std::addressof should be constexpr" (http://wiki.edg.com/pub/Wg21jacksonville/StrawPolls/P0304R0.html). My use case is similar to that of `optional<T>::operator->`, which is a constexpr function unless `T` is a user-defined type with overloaded unary `operator&`. Now that `addressof` is a constexpr function, there's no longer need for that restriction (I'll submit the corresponding LWG issue once we have a new draft). I'd like to be able to provide the same level of constexpr-ness on a piece of code that still supports C++11: https://github.com/eggs-cpp/variant/blob/master/include/eggs/variant/detail/visitor.hpp#L186-L218 > I am specifically soliciting comments on everything in the document that > involves a question mark. For P0036, "Unary Folds and Empty Parameter Packs", maybe bump `__cpp_fold_expressions`?
