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.
