Adjust phrasing

I think pointing out [Int]() from the code example is easier to follow
than [Element](), since the reader doesn't have to mentally map or
substitute a placeholder.

Reserve emphasis around new terms for when they're being introduced and
also explicitly defined.

No need to call out the book's style in the book itself.
