But this isn't a case of numifying a Pair, or of stringifying it - or of coercing it at all. If you've got a list of Pairs, you use a sorting algorithm that's designed for sorting Pairs (which probably sorts by key first, then uses the values to break ties). If you've got a list that has a mixture of Pairs and non-Pairs, I think that the sorting algorithm should complain: it's clearly a case of being asked to compare apples and oranges. When are you going to be asked to stringify or numify a Pair? Actual use-cases, please. Personally, I can't think of any. -- Jonathan "Dataweaver" Lang
