    // %        note 1: SORT_STRING (as well as natsort and natcasesort) might also be
    // %        note 1: integrated into all of these functions by adapting the code at    // %        note 1: http://sourcefrog.net/projects/natsort/natcompare.js
    // %        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    // -    depends on: i18n_loc_get_default
