One of the ideas I'm trying to convey is that the structure of the code is different from the syntax. With Clojure, special forms like def, if, etc, provide syntax in that each one has different rules for how their arguments get evaluated or, in the case of def, how the environment is changed. On top of that, you have macros which allow you to introduce arbitrary syntax. However, all Clojure code does have the same uniform structure. It's all composed of s-expressions, which are either atoms or other s-expressions enclosed in parentheses (for lists), braces (for maps), or brackets (for vectors). Thanks again for this feedback, having to explain this has given me some ideas for how to improve the chapter :)
