This was a deliberate choice. Most intro compiler/interpreter books don't do OOP. But most languages in wide use today are object oriented. That felt like a significant gap to me. One of the main goals with my book is to give people insight on how the languages they actually use work under the hood. Skipping objects and method dispatch would limit that.
