Incidentally, have you ever benefitted from group-by using a sorted-map, as opposed to, say, a hash-map? I'm asking because I'm a bit puzzled by the reasoning behind using this particular structure with the resulting ordering only vaguely related (i.e. in a manner which might be difficult to predict) to that of the input collection anyway... I haven't got a strong opinion on this, by the way, it's just that if there isn't some huge benefit to sorted-map which I can't yet see, perhaps a hash-map would make for a more versatile function?
