However this is +incorrect with C++20 coroutines, since an intervening `co_await` may cause the +coroutine to suspend and later be resumed on another thread. + +The lifetime of an object that requires being destroyed on the same thread must +not encompass a `co_await` or `co_yield` point. If you create/destroy an object, +you must do so without allowing the coroutine to suspend in the meantime. + +The check considers the following type as hostile: + + - Scoped-lockable types: A scoped-lockable object persisting across a suspension ---------------- PiotrZSL wrote:
