+# Pretty Print The Last Thing
+
+Clojure provides `pp` as a convenience macro for pretty printing the last
+thing that was output. If you are playing around with a function in the
+repl, trying to get the output just right, `pp` can come in handy.
+
+```clojure
+> (fancy-func)
+{:one {:a 1, :b 2, :c 3, :d 4}, :two {:b 2, :c 3, :d 4, :e 5}, :three {:c 3,
+:d 4, :e 5, :f 6}, :four {:d 4, :e 5, :f 6, :g 7}}
+> (clojure.pprint/pp)
+{:one {:a 1, :b 2, :c 3, :d 4},
+ :two {:b 2, :c 3, :d 4, :e 5},
+ :three {:c 3, :d 4, :e 5, :f 6},
+ :four {:d 4, :e 5, :f 6, :g 7}}
+nil
