All of the arguments from Swift 1 and 2 about why we didn't include this still seem relevant. To phrase it in generic programming terms, what algorithm would be generic over Arithmetic?

Um. I get that there are useful algorithms generic over floating-point vectors, and also useful algorithms generic over integer vectors. I’m still not sure what algorithms are generic over floating-point values (of any arity) and integers (of any arity).
