I think that tuples should remain what they are now. Static-length vectors
should be types on their own and interact with tuples, with structs and
with Array<…> in the same way.
newtype should be what enables extension of tuples:
newtype Money = (Int, Int)
extension Money: CustomStringConvertible {
var description: String {
return String(format: "$%d.%02d", arguments: [getSelfFirst,
getSelfSecond])
}
}
let x = (0, 42)let y = x as Money // errorprint(x.description) // error
let z = Money(0, 42)print(z.description) //=> $0.42
Here, getSelfFirst and getSelfSecond are placeholders for some syntax to
access the underlying type.
