clojure.core guide: error in declare example?

[jumarko]

The clojure.core guide demonstrates following example:

(declare func<10 func<20)

;; without declare you will receive an error similar to:
;; "Unable to resolve symbol: func10 in this context"

(defn func<10 [x]
  (cond
   (< x 10) (func10 (inc x))
   (< x 20) (func20 x)
   :else "too far!"))

(defn func<20 [x]
  (cond
   (< x 10) (func10 x)
   (< x 20) "More than 10, less than 20"
   :else "too far!"))

I guess, that func10 and func20 referenced inside the functions definitions should actually be "func<10" and "funct<20"
