Lightning Talk: Now in Our Lifetimes Cpp
summary
C++23 adds last‑second support for creating objects in raw memory so code that reads data from a file or a message queue can legally start object lifetimes where before it was undefined. The accepted feature is P2590 and the new APIs are std::start_lifetime_as and std::start_lifetime_as_array for implicit‑lifetime types. std::launder still does not start lifetimes. Some design details remain fluid but the proposal is standardized.
