A Tour of C++ Recognised User Type Categories
summary
Walk through which C++ user type categories actually change behavior across standards and why: shows concrete wording fixes (p0960, p1008), when bitwise copy is legal and why to check is_trivially_copyable, how union common initial sequences let you read matching prefix fields, why standard layout enables pointer reinterprets and offsetof, what became deprecated (POD and is_literal_type) and what is new in C++23 — implicit lifetime types and the start_lifetime_as facility for safely creating objects in raw storage.
