Yup. The four pillars of Object Oriented Programming are said to be: 1. Encapsulation 2. Data hiding 3. Polymorphism 4. Inheritance Perl doesn't really do data hiding very well (google for "Larry Wall shotgun"), but it does support the other three OK. I have not programmed in Perl using OO techniques in years. I think I have written one big Perl program that uses OO inheritance in 15 years. (Just lucky, I guess :) CPAN modules should be OO nowadays, just to avoid namespace clashes (all the good function names are taken). -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
