A return type for container methods.
Thread safety** - Container method return values are thread-unsafe*. A single-threaded application can safely assign the `returned<T>` value to a plain `T`. A multithreaded application *must* ignore the returned value because it may already be invalid by the time the function returns. Multithreaded applications can safely access the value inside messaging_handler functions.
