jslint 抱怨 __proto__ 是保留字

Question

这是有问题的代码：

hasOwnProperty: function (obj, prop) {
    var hasOwn = Object.prototype.hasOwnProperty,
        proto;
    if (hasOwn) {
        return hasOwn.call(obj, prop);
    } else {
        proto = obj.__proto__ || obj.constructor.prototype;
        return (prop in obj) && (!(prop in proto) || proto[prop] !== obj[prop]);    
    }
}

jslint 失败，同时吐出此错误：

Error:
Problem at line 653 character 29: Reserved name '__proto__'.
proto = obj.__proto__ || obj.constructor.prototype;

任何想法/解决方案？

这似乎让 jsLint 保持安静：

hasOwnProperty: function (obj, prop) {
    var hasOwn = Object.prototype.hasOwnProperty,
        proto = '__proto__';
    if (hasOwn) {
        return hasOwn.call(obj, prop);
    } else {
        proto = obj[proto] || obj.constructor.prototype;
        return (prop in obj) && (!(prop in proto) || proto[prop] !== obj[prop]);    
    }
}
