Basically, i really don't care much for Class::Struct, instead i opt for Class::MethodMaker, which handles inheritance. You can see an example of where i used that module at XML::Simple + Class::MethodMaker.

Yes, there are dozens of class-generation modules on CPAN, and Class::MethodMaker is clearly one of the leading contenders; I'm personally fond of my Class::MakeMethods, which I forked off of the original MethodMaker.

I've assembled a list that tries to outline some of their similarities and differences between the Class::* modules. It's incomplete and out-of-date, but it's a starting point.

That writeup was inspired by the poop-group's comparison; I think comparative resources like this can be of great value and I hope they continue to be produced.

I think an important criteria for an object module is the support channels. If it is not a simple module, then we need to be assured that we can get rapid help from the author or user community.

Carter's compass: I know I'm on the right track when by deleting something, I'm adding functionality.

Class::MethodMaker and Class::MakeMethods are indeed excellent modules.
I'm congradulating the authors, and especially, simonm and friends for the excellent documentation provided for the module. But let's set one thing straight. MethodMaker seems more compact than MakeMethods.

I'll definitely try both. OOP is my addiction anyway... I also want to give credit to Mr Damian Conway.
In my opinion, he has written one of the best programming books in (programming) history.
And I am very lucky that, the book is the "Object Oriented Perl." (http://www.manning.com/Conway/) He provides a whole chapter on Class::Struct and Class::MethodMaker.
I think MakeMethods is written after the book is published!!

Thank you all!
