Hi Swift community, I’d like to pitch this idea again.
Swift already has the pitched feature, but it is exclusive for tuples only.
SE–0071 allowed the use of keywords after the . in a member access, except for
those keywords that have special meaning by using back-ticks. However, members
starting with numbers are not special keywords and as already mentioned,
numerical members are already allowed in tuples.
I propose to extend that capability to the whole language and make that
behavior consistent. To disambiguate members starting with a number one would
need to use back-ticks.
// Enum
enum ErrorCode : String {
case `2345` = "my description for 2345"
case `123a` = "my description for 123a"
case `123b` = "my description for 123b"
}
let code = ErrorCode.2345
// Function
func `42foo`(label: Type, `12345`: Type, `0987something`: Type) { … }
// Tuple
(`1`: Int, `2`: Int)
My question is: would that be in scope for Swift 4?
