Swift – observations from Rust’s original designer
I hope ideas will flow the other way too, and Rust adopts some sugar from Swift.<p>I find `if let concrete = optional` <i>sooo</i> much nicer than `match optional { (concrete) => , _ => {} }`.<p>Rust has solid semantics that covers more than Swift. OTOH Apple has put their UX magic into the language's syntax. Some syntax shortcuts, like `.ShortEnumWhenInContext` are delightful.<p>The two combined will be the perfect language ;)
