Comparative Evaluation of Programming Paradigms: Separation of Concerns with Object-, Aspect-, and Context-Oriented Programming

There are many programming paradigms for the separation of concerns (SoC). Each paradigm modularizes concerns in a different way. Context-oriented programming (COP) has been developed as a supplement to objectoriented programming (OOP), which is one of the most widely used paradigms for SoC. It modularizes concerns that are difficult for OOP. In this paper, we focus on three paradigms OOP, aspect-oriented programming (proposed as a supplement to OOP that has a different approach from COP), and COP and study whether COP can modularize concerns better than other two paradigms in given situations. Then we determine the reasons why COP can or cannot better modularize concerns.
