Serialization in C++ has never been easier! But wait, there's more
summary
Demonstrates how Proposal P1717 plus upcoming reflection and consteval/meta facilities produce an automatic JSON serializer that prints ints, strings, vectors, optionals and nested structs without per-type iterate_members boilerplate. Uses compile-time meta: count data members, get nth member name, unqual_id/unquote and fragment injection to generate code, and metaclasses to add members or make types noncopyable/movable. Runs on a prototype hosted at cppx.godbolt.org (log3/meta); several features (template value reflection, some injections) are still incomplete but the serializer demo works.
