To me it's not the trivial cases like this that make type inference useful. It's when you get longer types like `Arc<Mutex<HashMap<String, String>>>`. Granted, that could be solved with a `type` declaration (or `typedef` in C++) but it's still convenient to be able to say: `let mut x = Arc::new(Mutex::new(HashMap::new()));` and let the compiler figure out the rest based on usage. |
