I should also probably point out that the get-in/assoc-in/update-in
family of functions is a much better way of working with nested maps
than a zipper:
(-> {:foo {:bar {:baz 1}}}
(assoc-in [:foo :bar :greeting] "hello!")
(update-in [:foo :bar :baz] inc))
;; => {:foo {:bar {:greeting "hello!", :baz 2}}}
