template<class Istream, class T> Istream&& operator>>(Istream&& is, T&& x);
Constraints: The expression is >> std::forward(x) is well-formed when treated as an unevaluated operand andIstream is publicly and unambiguously derived from ios_base.
Effects: Equivalent to:is >> std::forward(x);return std::move(is);
