--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Well, guess there is a bug on the gcc side. For reflection which differentiates between type aliases and types, it might not be a good idea to print ^^std::meta::info or ^^std::nullptr_t when we actually mean ^^decltype(^^int) or ^^decltype(nullptr) or even ^^const decltype(^^int) or ^^const decltype(nullptr) etc.
