问一下，Hamibot脚本如何自定义类

写了个简单的示例代码

auto.waitFor(); 

class User {
    constructor(id, name) {
        this.id = id
        this.name = name
    }
    Getid() {
        return this.id
    }
    Getname() {
        return this.name
    }
}

let 张三 = new User(123, '张三')
toastLog(张三.Getid())

运行后报错，日志提示identifier is a reserved word
