[swift-evolution] [idea] errors in properties

[Gor Gyolchanyan via swift-evolution]

I’ll just cut to the chase:
Why is throwing from get, set, willSet and didSet disallowed?

var login: String {
        willSet throws {
                guard newValue.count > 5 else {
                        throw LoginError.loginTooSmall
                }
        }
}

try login = “JebediahKerman” // totally fine
try login = “Bob” // throws `LoginError.loginTooSmall`
