As far as I can tell, you agree with the articles main point. `plus` is a honest name for adding days to a date but dishonest when it comes to adding months. `advanceMonths` is an awkward but more honest name for adding months. An even more honest name would be `addMonthSameDayButCapIfShorter()` or something like that which reflect the gnarly behavior. A weird operation deserves a weird name. I don't like if `advanceMonths` returns an interval though, since this indicate that the interval is a meaningful unit separately from the initial date. It should return the new date, not an interval.
