Class::Generate is a Perl5 module to simplify creating class hierarchies. It offers typed or untyped scalar, array, and hash members, required members, private members, methods (both instance and class), and other common features of object- oriented software development. Of course, you can implement all these things without a special module, but doing it via Class::Generate is much, much more concise. And furthermore, it's much less error prone: if you are using Perl's -w flag, Class::Generate will catch many class specification and usage errors. WWW: http://search.cpan.org/dist/Class-Generate/
