Looking at ToC, the odd thing about Clojure for the Brave and True is that the very last chapter is:<p>Chapter 13: Creating and Extending Abstractions with Multimethods, Protocols, and Records<p>... This chapter serves as an introduction to the world of creating and implementing your own abstractions.<p>Wouldn&#x27;t it make more sense to introduce tools for creating your abstractions at least in the first part of the book?
