The metric is: is there a way which keeps my subclass a) isolated and encapsulated from any implementation details of the superclass b) while later letting me break this subclasses’ encapsulation iff I so choose? I explained how the approaches known so far fail to satisfy this metric. (Except I missed the fact that xdg pointed out.)

Ruby offers that, which is why I said Perl 5 is not on par with it. (Turns out it is.)
