在框架中，我正在开发，我已经构建了允许定义私有(private)和 protected 属性和方法的机制。
我在 ES5 规范中发现唯一的能力是使用 arguments.callee
像这样:

descriptor.method = function () {
    if (__callerIsProptected(arguments.callee.caller.caller, cls))
        return value.apply(this, __defaults(_.values(arguments), defaults));
    throw 'Attempt to call ' + access + ' method "' + cls._name + '::' + name + '"';
};

至于在严格模式下调用 arguments.callee 和 arguments.caller 导致抛出异常，是否有任何方便的替代方法来做到这一点？

更新 - 添加了整个被调用的函数代码

    function __descriptor(cls, type, name, descriptor, access) {
    //protected private non-function descriptor.value is replaced by get/set pair
    if (access !== 'public' && type == 'property') {
        delete descriptor.value;
        delete descriptor.writable;
        _.isFunction(descriptor.get) || (descriptor.get = function () {
            return this.__get(name);
        });
        _.isFunction(descriptor.set) || (descriptor.set = function (value) {
            return this.__set(name, value);
        });
    }
    //remove uselesses
    if (_.isFunction(descriptor.get) || _.isFunction(descriptor.set)) {
        delete descriptor.value;
        delete descriptor.writable;
        if (!_.isFunction(descriptor.get)) {
            descriptor.get = function () {
                return this.__get(name);
            };
        }
