C++17: The Library Features
summary
C++17 adds concrete, usable library features: a non-owning string_view lifetime issues with a literal suffix sv and matching hash to std::string; value wrappers optional/variant/any (variant can become valueless by exception); std::filesystem with path parsing changes, relative-path semantics and some API breaks vs Boost; parallel STL execution policies (seq, par, par_unseq); node-based map/set extraction that avoids reallocation; fast to_chars/from_chars conversions, shared_ptr for arrays, new atomics and search algorithms.
