    // %          note 1: The examples are correct, this is a new way
    // %        note 2: This function deviates from PHP in returning a copy of the array instead
    // %        note 2: of acting by reference and returning true; this was necessary because    // %        note 2: IE does not allow deleting and re-adding of properties without caching
    // %        note 2: of property position; you can set the ini of "phpjs.strictForIn" to true to
    // %        note 2: get the PHP behavior, but use this only if you are in an environment
    // %        note 2: such as Firefox extensions where for-in iteration order is fixed and true
    // %        note 2: property deletion is supported. Note that we intend to implement the PHP    // %        note 2: behavior by default if IE ever does allow it; only gives shallow copy since
    // %        note 2: is by reference in PHP anyways
    // *     example 1: data = {d: 'lemon', a: 'orange', b: 'banana', c: 'apple'};
    // *     example 1: data = uksort(data, function (key1, key2){ return (key1 == key2 ? 0 : (key1 > key2 ? 1 : -1)); });
    // *     results 1: data == {a: 'orange', b: 'banana', c: 'apple', d: 'lemon'}    // *     returns 1: true
