As I said, ref() should be only used with objects if you really want, explicity, an object blessed in the class FOO, soo, without care about inheritance.

I know that this is possible, as I show in the previous node, what I said is that I never saw this in use! I never saw a code that want's to use the internal object data, HASH, ARRAY,... as a normal data! And I think, that shouldn't be used, since this is not a good thing when we are talking about OO.
