Trait objects seem not to be documented at all in the book, which together with their mandatory lifetime bound annotation makes them almost undiscoverable. Fortunately, there are some nice blog posts by @huonw, but they are unlikely for a user to stumble upon.

Also, the only occurence of 'trait object' in the reference is following sentence, which is strange:

Likewise, supertrait methods may also be called on trait objects.

I started to write up some docs on this, and then realized I was just repeating http://huonw.github.io/blog/2015/01/peeking-inside-trait-objects/ but worse. @huonw previously said that we can use this content if we wanted, so I made some tweaks and integrated it into the book.
