New user-defined literals for standard library types, including new built-in literals for chrono and basic_string. These can be constexpr meaning they can be used at compile-time. Some uses for these literals include compile-time integer parsing, binary literals, and imaginary number literals. ...

User-defined literals allow you to extend the language and add your own syntax. To create a literal, define a T operator "" X(...) { ... } function that returns a type T, with a name X. Note that the name of this function defines the name of the literal. Any literal names not...
