This removes a non-standard extension to std::any which causes errors for valid code, due to recursive instantiation of a trait that isn't supposed to be in the constraints. It also removes some incorrect constraints on the in_place_type<T> constructors and emplace members, which were preventing creating a std::any object with another std::any as the contained value. 2020-04-24 Kamlesh Kumar <kamleshbhalui@gmail.com> Jonathan Wakely <jwakely@redhat.com> PR libstdc++/90415 PR libstdc++/92156 * include/std/any (any): Rename template parameters for consistency with the standard.
