Personally I don’t see the latter as an issue, at least not in that particular example of yours, because you can always look up the type of your labeled tuple.
Is there any benefit gained from labels in tuple destructuring? let (x: x, y: y) is redundant to my eyes. If we ban reordering now, than I don’t see choosing different names in tuple destructuring as a strong argument of allowing labels there let (x: a, y: b). They’re literally the same as one would write comments inside the destructured tuple let (/* my x */ x, /* my y*/ y). -- Adrian Zubarev Sent with Airmail Am 5.

I'm a confused human. Now I write: let (y: y, x: x) = tuple // Currently, does the right thing, even though I'm confused. let (y: y, x: x) = tuple // Without tuple reordering, this produces an error, which corrects my confusion. let (y, x) = tuple // Oops. I'm out of luck. ```
