in reply to A couple questions about object oriented Perl programming: inheritance and error handling
These are covered in "perldoc perltoot" (Run at command line).
See the sections titled "Multiple Inheritance", "Inheritance" and "Overridden Methods".
These days, monks prefer to use "post-modern OO" implementations like Moose or it's minimalist imitation, "Moo".
Re: Error handling

That includes examples of globalized error handlers.
Re: Redirection exit vs return
I think exit is fine. Others may have esoteric reasons for preferring "return".
