C++23 Standard Library Preview
summary
Survey of concrete C++23 payloads and current status: ranges get many new views and algorithms (zip, fold, starts_with, chunk/slide, and ranges to for container materialization), I/O extends std::format with compile‑time checks plus std::print and span_stream, containers add flat_map/flat_set, std::stacktrace appears, more constexpr on type_info/variant/optional, out_ptr and optional monadic helpers land, modules settle on import std and import std.compat, and an experiment shows import std running roughly 5–25× faster than header includes.
