OO Design Principles/Patterns

As someone who arrived somewhat late to the OO game, I have take every 
opportunity to learn some of the principles of OO design and use.  I 
have been using Moose for a couple of years, primarily in the context of 
Catalyst and HTML::FormHandler.  Lately though, I am studying the book 
'Design Patterns - Elements of Reusable Object-Oriented Software', which 
comes highly recommended in OO land.

I am wondering if anyone in the Moose community is: 1) aware of the 
book, 2) used the patterns with Moose, and 3) has taken time to write 
about implementing some of the patterns with Moose.

The only thing I've seen referenced is how Moose 'almost' can be used to 
create an abstract class with roles.  This might be good subject matter 
for a book on Moose!
