Okay, now after actually reading the documentation I can come back with an actually correct response!
You should only have to change one function: > (defn make-node [n children] > (vec (cons (first n) children))) Your issue was that your original `make-node` function didn't return a vector, it returned a ConsCell (with a vector as its tail). This meant that your new node no longer returned true for "children", that is it identified itself as a leaf. By making `make-node` return a vector (vec turns any sequable thing into a vector) your `make-node` now returns a valid branch node, so z/next behaves as you want it to.
