Denis Blank	fdd9a061c4	Make promise_base default constructible ... * This makes it possible to use promise_base for optional promises directly rather than wrapping it as optional<promise_base<...>>. * Invalidate the promise_base after its first usage. * Expose an `operator bool()` to make the validility accessible. * Remove the no longer needed private promise_no_init_arg_t tag.	2019-03-08 18:13:40 +01:00
