string_view
summary
string_view is a Library Fundamentals TS class that models a constant contiguous character sequence as a non-owning pointer+length (four char-type specializations), with cheap constructors from pointer+length or std::string (implicit) and one that traverses a C string to find length. It removes temporary std::string allocations so simple parsing examples go from multiple allocations and copies to no heap allocations, supports remove_prefix/remove_suffix, but gives no null termination and forces caller-managed lifetimes and thread-safety.
