Errata for Programming Clojure

#39403: It is mentioned twice that "Clojure relies on Java's BigDecimal class for arbitrary-precision decimal numbers."

The first time with a reference to the bottom of the page and the second time with the URL directly.--Jeff Heon

#39434: - You can also pass a nonstring to shout and see that
- Clojure enforces the :tag by attempting to cast the
- argument to a string"

Nope, otherwise this would fail too:

user> (defn #^{:tag String} shout [#^{:tag String} s] s)
user> (shout 10)
10

The :tag definition allows Clojure to select .toUpperCase from String class in compile time and when shout is invoked ClassCastException is thrown because it is invoked on instance of wrong type.

Without :tag definition .toUpperCase must be resolved during shout invocation which fails if not defined for given argument class.

#39813: user=> (import '(java.util Random Locale) '(java.text MessageFormat))
java.text.MessageFormat

Hence, the last import was returned instead of nil...--Joe Straitiff

#39602: (for [n (whole-numbers) :while (even? n)] n) yields an empty list and not (0) as the seq from (whole-numbers) starts from 1. (sugg: replace even? by odd? to get (1) as an example)--Martial Boniou

#39147: The analysis of stack-consuming-fibo is a bit misleading. It generates a number of stack frames exponential in n. (This is also proportional to n, but that is a much weaker statement). There is also a small grammar error in that sentence.--Chris Gray

#39359: the example create-runonce defines the (fn [& args]) but doesn't actually apply the args to the function. this makes the example in the book do nothing but print a newline.

the (reset! result (function))
should be
(reset! result (apply function args))

this will make it work
--David Budworth

#39756: In the following text,

". . . until the unlucky day that you picked a local name like start, which
collided with a name inside bench:
(let [start 1 end 2]
(bench (+ start end)))
) {:result 3, :elapsed 1228277342451783002}}
bench captures the symbol start and binds it to (System/nanoTime). All of
a sudden, one plus two seems to equal 1228277342451783002."

Shoudn't the result be along the lines of:
{:result 1228277342451783002, :elapsed 39000}} ?--Jeff Heon
