Copy + paste error

[mdjnelson]

Thanks for this great book guys. As a newbie to DDD it was very helpful (though I have to admit I had to re-read a few parts to get my head around it, and will probably keep referring back to this book for a while :P).

Just noticed a minor issue - the phrase "By using the self keyword, we don't" is used under the chapter title "Value Objects" at the start of the paragraph on page 70. I believe this is a copy + paste issue as it is also used on page 75.
