 - **Macro Integration**: Macros use `!` as a postfix operation.
 - **Type Casting**: `as Type` provides explicit type conversion at the expression level.
 - **Error Propagation**: The `?` operator enables early returns for `Result`/`Option` types.
+- **Arrow Closures**: `(params) => expr` for concise anonymous functions.
