What's New In The C++14 Library
summary
C++14 delivers concrete library changes: new user literals (binary, time suffixes, complex 'i'), digit separators, and utilities like make_unique, exchange and make_reverse_iterator; iterator/unordered APIs gain heterogeneous lookup and value‑initialized null iterators; metaprogramming gets integer_sequence (make_index_sequence) to unpack tuples; formatted I/O gets quoted for round‑trip strings; shared mutex/lock types arrive for reader/writer scenarios. Several proposals (optional, splice, array extensions) move to separate TSs and some ABI/constexpr choices are deferred.
