Just after Sawyer X gave a quick review on my chapter 2, on Modern OO programming, I am making the second chapter PDF file available on the book website.
Before leaving you reading the document, I would like to make it clear that i really want to make this chapter this way, presenting first Moo, then Mouse, and finally Moose. I know that the order is not cronological. It is just the order of presenting, each time, a more complex module. I didn't know Moo, Mouse or Moose. I had to learn them all from scratch, and I did it in this order. And I liked it.
Other than that, please, comment and suggest any correction you find relevant.
