This container can hold a type-erased instance of any completion
    handler, or it can be empty. When the container holds a value,
    the implementation maintains an instance of `net::executor_work_guard`
    for the handler's associated executor. Memory is dynamically allocated
    to store the completion handler, and the allocator may optionally
    be specified. Otherwise, the implementation uses the handler's
    associated allocator.
