I think something like "date.add_months()" would be better than the proposed
monthdelta. The monthdelta proposal suggests that addition is something
well-defined and rigourous, which is not really the case here (for example, if
you add a monthdelta and then substract it again, I'm not sure you always get
back the original date).
