They do need to co-operate over DESTROY.

Yes, but not more than any other form of inheritance does. If you subclass a class, and define a DESTROY method in your subclass, without calling DESTROY in the superclass, things are likely to break. Your DESTROY method should always contain something like (for single inheritance):

    $self -> SUPER::DESTROY if $ISA [0] -> can ("DESTROY");

regardless whether you use Inside-Out objects or not.

Good point.

I guess I just worry about DESTROY with inside-out objects more because having a correct DESTROY block suddenly becomes something you need for every class with its own state, rather than something you only need for rare classes that fiddle with external resources.
