Chapter 7. Transformations as First-class Citizens

In this chapter we are going to cover advanced techniques, taking advantage of some of Clojure's powerful tools inherent to its functional nature. We'll discuss functions as privileged language constructs in the following recipes:

• Building a recursive descent parser using trampoline
• Implementing a reusable mini-firewall using transducers
• Building a little unification engine with the continuation-passing style
