constexpr in_place_t in_place{};		(library fundamentals TS)

std::experimental::in_place is a constant of type std::experimental::in_place_t that is used to disambiguate the overloads of constructors and member functions of that take arguments (possibly a parameter pack) for in-place construction of some value.
