When I started learning Clojure, I did not want to be a casual user that shyed away from Clojure's native syntax, preferring to do as much as possible in Java. To that end, I discovered some graduate computer science Clojure exercises and started working them.
I know about 4Clojure, but these exercises made my head hurt, but as the Gary Larson cartoon told it, it was a "good kind of hurt". By forgoing the use of flatten and trying to roll my own, I gained some insights of how sequences are constructed and what they actually are. However, coming across the exercise to return the skeleton of a tree, I immediately thought of meta data, but I'm not sure this exercise was designed to encourage the students to use the clojure.zip routines. So, my question is, using elementary primitives, is it reasonable to return a list without its leaves, or do you really need the clojure.zip functions?
