C++23 Standard Library Preview
summary
C++23 delivers concrete changes: ranges gain zip and fold views plus starts_with and pipe customization; formatting adds std::format compile-time checks and a new print header for file/console output; I/O gets span_stream for user buffers; containers add flat_map/flat_set; std::stacktrace arrives for debugging; more constexpr support lands for type_info, std::variant and std::optional; modules propose an import std plus std.compat split; compiler support already appears (gcc 12) and module builds report ~5–25× speedups.
