It would be nice to have an equivalent of any_completion_handler where the handler can be invoked multiple times. A real-life use case is a user-registered RPC handler in a middleware library, where the user wants to specify an executor via which the RPC should be posted.
It would be preferable if such a multi-shot handler were copyable, the same way as std::function is copyable.
