Making It More Functional

Ted Neward goes through a code kata with several programming paradigms in the latest Working Programmer column. Being a coding polyglot is all the rage nowadays, and understanding multiple paradigms is essential to being a well-rounded developer. Ted goes through procedural style, modifies it to be object-oriented, demonstrates how to use meta and then dynamic programming. Finally, he makes it more functional. The proposed solution adds an aspect of functional programming, but it can be taken further.
