I can't imagine there would be. @autounwrapped (or whatever) is a purely compile-time thing which tells the compiler to automatically insert a `!` operator if it will make the expression typecheck. Other than that compile-time behavior, `!` is an exact synonym for `?`. -- Brent Royal-Gordon Architechies _______________________________________________ swift-evolution mailing list [email protected] https://lists.swift.org/mailman/listinfo/swift-evolution
