A proposal along these lines appears to already be in the works. However, tuple arrays still aren't quite first-class types—you can't even loop over them. Nor does that address other cases like ring buffers with a generic size.
Tuple arrays are a great way to get some extra mileage out of an existing feature, but they're not a 100% solution.
