I strongly agree: Fixed-size vectors are a well known and simple concept that shouldn't be conflated with tuples.

Afair there was a time when Swift had no set-type, and I think we are lucky that it was added, instead of forcing us to use other collections instead.
Mixing array and tuple feels like having a switch for array to behave like a set...
