    var DefineProperty = /** @class */ (function () {
        function DefineProperty() {
            Object.defineProperty(this, "b", {
                enumerable: true,

            });
        }
        return DefineProperty;
    }());
    var RawAccess = /** @class */ (function () {
        function RawAccess() {
            this.b = 2;
        }
        return RawAccess;
    }());
