The only case here that might be *somewhat* sensible is the userdata argument of array_walk(), which could be used to keep persistent state between callback invokations -- with the WTF moment that the final result after the walk finishes will be unchanged. Nowdays, this is much better achieved using a closure with a use-by-reference.
