Description

token_

The experimental::as_single_t class is used to indicate that any arguments to the completion handler should be combined and passed as a single argument. If there is already one argument, that argument is passed as-is. If there is more than argument, the arguments are first moved into a std::tuple and that tuple is then passed to the completion handler.
