Summary
This episode examines C++26's define_static_string and define_static_array features (from paper P3491R3) that finally solve a long-standing problem: persisting compile-time constructed data to runtime without manual copying or oversized arrays. Jason demonstrates how these reflection-based utilities work with any range-like types, automatically creating appropriately-sized static arrays at compile time. The solution eliminates the need for the traditional workaround of copying constexpr data into fixed-size arrays, which Jason has been advocating for since his influential 2017 'constexpr ALL the things!' talk.
