Fail to define a Class in Clojure?

Question

I was following the example on Clojure in Action Page 326,

 (defn new-object [klass]
  (fn [command & args]
    (condp = command
      :class klass)))

Then I typed: (def cindy (new-object Person))

It gives me: CompilerException java.lang.RuntimeException: Unable to resolve symbol: Person in this context, compiling:(/Users/sdfsd/clj/testlein/src/testlein/sdf:22:12)

If I change Person to "Person" or 'Person, it works. But I believe that is not the right way to solve this problem because Person should be a class and "Person" is :name of the class. Could someone please tell me why I am having this problem? Thanks!

You have to import the class, clojuredocs.org/clojure_core/clojure.core/import — tangrammer

 (import package-and-name-of-your-person-class)

Or without import, use as parameter in the function call package-and-name-of-your-person-class instead of Person

(def cindy (new-object package-and-name-of-your-person-class))
