Title: Add an example of a trait used within a trait.

It's very difficult to find an example of a trait being used inside of another trait anywhere. The only good example I could found was the commit that allowed this behavior, which is a bit too obscure in my mind: 779eafccbdb2a404ceabf2a4a2ad3d7b04eaf498

Please close if I missed an obvious piece of documentation.
