// % 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
// % note 3: Since JS objects' keys are always strings, and (the
// % note 3: default) SORT_REGULAR flag distinguishes by key type,
// % note 3: if the content is a numeric string, we treat the
// % note 3: "original type" as numeric.
// - depends on: i18n_loc_get_default
// * example 1: data = {d: 'lemon', a: 'orange', b: 'banana', c: 'apple'};
// * example 1: data = krsort(data);
// * results 1: {d: 'lemon', c: 'apple', b: 'banana', a: 'orange'}
// * example 2: ini_set('phpjs.strictForIn', true);
// * example 2: data = {2: 'van', 3: 'Zonneveld', 1: 'Kevin'};
// * example 2: krsort(data);
// * results 2: data == {3: 'Kevin', 2: 'van', 1: 'Zonneveld'}
