That's the single measurement that makes Perl 5 OO inadequate? Nothing else matters? That's the only thing you are going to use when you compare other languages?

Perhaps you should have chosen a better title for your node: "Perl OO encapsulation inadequate", because that's all you're talking about and its a very poor judge of a language's adequacy. Your claims that Perl is deficient come without anything Perl doesn't allow us to do or a way in which it fails to help us get work done.

I think, then, that I'd have to put your argument in the category of "mathematical purity wanking" because you haven't shown any inadequacy in any other dimensions I explained in my original reply. In everyday life, this issue is something far down on the list of things people care about.

As I said earlier, there are better things to argue about if you want to call Perl's OO inadequate. A better start is Perl's lack of objects. :)
