Due to the restriction on repeated names (e.g. Point(x, x) is illegal), if you want to "throw away" intermediate matches, you will have to either have to come up with new names (Point(unused_1, unused_2)) or use the "_" as currently instituted (Point(_, _)) and "else:" does not cover that insofar as I can tell. Would it be possible here to use a syntax/symbol that is illegal instead of _? I think this has been mooted but my favourite (so far) would be "?" so you have "case ?:" and "Point(?, ?)". Would ?name then work instead of ".name" as well? Not sure that makes its use more/less/equal consistent with the previous suggestion. Apologies if this has been discussed, I have followed the thread(s) but I might well have forgotten or missed something!
