std::experimental::source_location::source_location

constexpr source_location() noexcept;	(1)	(library fundamentals TS v2)
source_location( const source_location& other ) = default;	(2)	(library fundamentals TS v2) (implicitly declared)
source_location( source_location&& other ) = default;	(3)	(library fundamentals TS v2) (implicitly declared)

1) Constructs an source_location object whose values are implementation defined.

2-3) Implicitly declared copy and move constructors.

other - another source_location to copy from
