Comments about intention are good. Yes, an experienced dev can infer intent from context (name, project, 'culture'), and even a smart beginner can read ahead to infer intent. But the comment resolves ambiguity in the advanced dev's mind, and saves the beginner's mind from the difficulty of read-ahead inferences (of which he may have several going at once). I say, keep it.
