Wrapping Up

We covered a lot of ground in this chapter, from the general use of abstraction in programming to some (but not all) of the specific abstraction mechanisms Clojure provides. We explored creating concrete abstractions using protocols in Clojure and had some fun in the process!

But there’s still more. Clojure’s macro implementation is easy to learn and use correctly for common tasks and yet powerful enough for the harder macro-related tasks. In the next chapter, you’ll see how Clojure is bringing macros to mainstream programming.
