I'm just trying to think if this causes any surprising behavior, either because some string is unintentionally cast to a date or interval type, or because it doesn't fully work in all cases (see the other ticket). How much do we need to support this? If it's not a standard behavior across DBs, I'd kind of prefer to have people write more explicit casts for such a thing. Do we cast strings to other types implicitly though?
