Comment (by ayeshrajans):

 Thumbs up for skipping the test in pre-5.4 PHP versions and calling it a
 day. The polyfill simply returns true if the object is of class
 `ResourceBundle` and doesn't inspect anything deeper. Until PHP provides
 means to inspect the internal class implementations for `count_elements`
 hook, `is_countable` polyfills won't be perfect anyway.
