The former phrasing seemed to suggest that we _must not_ annotate types _unless_ there are multiple possibilities. In fact, we are allowed to add redundant annotations. Cases where no annotation is needed _despite_ multiple possible types -- e.g. `let n = 8` -- are, presumably, intentionally left out here, so not touching that.
