Compile-time reflection, Serialization and ORM
summary
Describes implementing compile-time reflection in Modern C++ using void_t, tuple, index_sequence, variadic templates, constexpr, macros and C++17 features; claims a compact <500-line library versus boost.hana’s ~3,000 lines, auto-generates metadata via macros, serializes structs to JSON/XML/MessagePack, builds a working ORM that generates SQL and maps rows to objects, supports up to 120 fields, and notes limits: no private members or member functions and lambda captures are not reflected.
