ok. Now one more question please: your solution looks also slightly more complex from the user's perspective: he has to deal with the *parser* object and the future object (returned by schedule-parse).
So the question is: what does your solution provide that the sketch of my solution does not ? Do you see my solution harder to implement ? Do you see your solution more generic ?
