Even going backwards, it's still not ok...
>From the -reverseObjectEnumerator 'special considerations' section of
the documentation:
"When you use this method with mutable subclasses of NSArray, you must
not modify the array during enumeration."
And from NSEnumerator:
"Some enumerators may currently allow enumeration of a collection that
is modified, but this behavior is not guaranteed to be supported in
the future."
