### async_immediate

Launch a trivial asynchronous operation that completes immediately.

    template<
        typename Executor,
        typename NullaryToken = default_completion_token_t<Executor>>
    DEDUCED async_immediate(
        const Executor & ex,
        NullaryToken && token = default_completion_token_t< Executor >(),
        constraint_t<(execution::is_executor< Executor >::value &&can_require< Executor, execution::blocking_t::never_t >::value)||is_executor< Executor >::value >  = 0);

    template<

    DEDUCED async_immediate(
        ExecutionContext & ctx,
        NullaryToken && token = default_completion_token_t< typename ExecutionContext::executor_type >(),
