Again, I’m not attached to `__toString()`. Having another helper method or a special formatting constant, as suggested by others in this thread, would likewise be a viable option. I’d merely prefer to have a built-in way of parsing*and* composing time intervals as per the ISO specification, making the API consistent and easing communication with non-PHP systems.
Would a reasonable way forward be to have such a named method, and have it throw an exception if the instance is not representable in that form?
That way, you'd be guaranteed that new DateInterval($period->toIsoPeriodString()) would result in an equivalent object, rather than discarding special relative values.
