Good job. I am currently looking for a module like yours. Currently was focused on CGI::Application.
I understand that developing this kind of mohule is a lot of fun and will help you learn a lot and become a better programmer - no questions about it.
Still, what was the reason why you did not want to consider CGI::App? What functionality was missing in CGI::App? What error I may do if I commit myself to CGI::App?
Just wondering if I forgot to ask some important question... I have nothing against your code, I read tilly's comments elsewhere and can just hope my understanding of perl will match his some day...

To make errors is human. But to make million errors per second, you need a computer.
