Issues when working with Clojure for the Brave and True #12
Description
I've been following along with the book Clojure for the Brave and True and I've noticed a few issues. In the book examples, (require) is used, when it should be (:require).
Additionally, some of the functions are referred to in the book, but their code is not shown in the book itself (e.g. colorize, strings-as-characters, etc.) Perhaps the tutorial is meant to go along with the code repo (which does work), but I was trying to build it from scratch using only the examples in the book and I couldn't get it to compile without downloading this repo and changing certain things and copying over the missing functions.
