[swift-evolution] [Pitch] Numeric enum cases

[Adrian Zubarev]

Have we already discussed this somewhere?

enum MyEnum {
    case 0
    case 1(String)
}

// or

enum MyEnum {
    case `0`
    case `1`(String)
}

let zero: MyEnum = .0
let one = MyEnum.1("Swift")

switch zero {
     
case .0:
   print("zero")

case .1(let string)  
   print(string)
}  

Tuples have this .# syntax, where the number is the index of the tuple value. Can’t we allow this on enum cases as well?

This is additive and something for phase 2, but I’d like to know if we want to allow this?! :)
