array_key_exists() was converting collections to arrays before checking if a key exists, which is an O(n) operation (which also has the annoying side effect of changing int-like string keys to int keys.) This diff makes array_key_exists natively support collections (which also addresses the pesky int-like string key -> int key issue).
