C++, Java, C#, Python, Ruby, JavaScript are the most powerful object-oriented programming languages, if language power would be defined as the number of features available for a programmer. EO, on the other hand, is an object-oriented programming language with a reduced set of features: it has nothing by objects and mechanisms of their composition and decoration. We are trying to answer the following research question: "Which known features are possible to implement using only objects?"

翻译：C++、Java、C#、Python、Ruby、JavaScript 是最强大的面向对象编程语言，若语言能力定义为程序员可用的特性数量。而 EO 则是一种特性精简的面向对象编程语言：它仅保留对象及其组合与修饰机制。我们试图回答以下研究问题："已知的哪些特性可以仅通过对象实现？"
