On page 26 you explain the use of anonymous functions with the example

(require '[clojure.string :as str])
(filter indexable-word? (str/split "A fine day it is" #"\W+"))
-> ("fine" "day")

You explain the invocation of split with “The call to split breaks the sentence into words, …”.
Probably you could mention that with #"\W+" a regular expression is defined (which will probably be explained later in the book).

I’ve done a bit better and added a regular expressions subsection in the Reading Clojure section. Thanks!

I have just seen that you use a regex on page 32 as well, and there you explain the reference.

split splits the string around the regex matches (for whitespace),

Such a note could be used on page 26 as well. But a “regex” subsection is perfect, this section can be referenced from all usages.
