A fair degree of privacy is gotten by constructions like you discuss. You have very well described the use of closures for private data and methods.

What I really applaud is your conclusion. Perl is not an enforced OO language. Like C++, it is a mixed language with support for OO but no requirement. Unlike C++, perl's OO constructs get by with conventions about what methods may be called reliably. We name private methods with a leading underscore, and we don't care what happens to people who call them from outside.

This voluntary cooperative model of OO gives the screaming horrors to Smalltalkers and other purists, but it leaves a lot of space for us to work in. Mixed model languages are so much more comfortable to work in. The design of a program does not have to be pounded into any One True Shape.
