Rethinking Object-Oriented: Clojure and the Expression Problem

About this Presentation

What is the Expression Problem? The question is far from academic: any programmer working in mainstream object-oriented languages is bound encounter it. As a young language on the JVM, Clojure has the opportunity to step back from mainstream approaches to object-oriented design, and get back to core concepts like type and polymorphism. Clojure, while not an object-oriented language itself, offers features that can achieve the same goals as OOP with greater flexibility.

This talk will explain what the expression problem is, why it matters, and how Clojure's Multimethods, Protocols, and Datatypes can help solve it.
