源码类实现子集采用 `class Name: Base { field: TypeName function method(self: Name): ResultType { ... } }`;基类可省略,执行环境须提供 Object。成员函数沿用既有 function 语法,接收者 self 为显式首参数。普通类字段按基类字段、再本类字段的顺序接收位置构造实参。这里记录实现范围,不确认语言文档中的全部候选构造语法;详细限制见[名义类型](types.md)。
`await expression` 解析为 ExprKind::Await { operand },优先级与前缀负号同级,成员/调用绑定更紧;例如await task.result()等待该调用的返回对象,(await task).field先等待task。await按表达式前缀位置识别,不引入async函数声明。执行是否允许等待由调用上下文决定,见字节码VM的Await章节。
