I think that it's unfortunate they stuck with that example instead of the classic point class example for positional args. In general the positional destructuring is not great, but there are some cases where it is nice and readable. Because of that I'm glad it's not the default that all record classes get it.

    var (f, l) = person;

is gross and hard to understand.

    var (x, y) = point;

is simple and readable.
