Well thanks to everyone for the comments. I used the perlshop code as a vehicle to setup something so I could attempt an administrator. I never would have figured out a store from scratch. I needed one that worked like I expected a store to work. I learned how to effectively use the ptkdb debugger with this, which is probably it's biggest benefit for me. When Perl6 comes out, I will probably try to rewrite my own store, using the perlshop store as a general layout.
