All Perl classes are friends, if they use the most common method of object instantiation, which is a blessed hash reference. If you use that method, then any class may access the instance data of any class object, regardless of the class to which the objects belong. Perl is a very friendly language. As Larry says: "Perl doesn't have an infatuation with enforced privacy. It would prefer that you stayed out of its living room because you weren't invited, not because it has a shotgun". Programmers can hide internal instance data, but it does take some work. You can put data in package-scoped lexical variables, for instance. Sometimes programmers will indicate private methods with a naming conventions, such as a single underscore beginning a method name. But those are only conventions, and the language does not enforce the restricted access. -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
