An Implementation of Open Modules in AspectJ

Aspect-oriented programming languages provide advice to modify the behavior of programs. Some current languages, notably AspectJ, provide few limitations on advice, so new advice can change the behavior of existing programs without any restrictions. Changes to the base code can also a#ect the behavior of existing advice in an unexpected manner. Open modules is one proposal to solve the problems above. It is defined for a small functional aspect-oriented language, and has the benefit of a formal definition of its behavior. There is, however, no implementation for Open Modules in an existing aspect-oriented programming language. Aspect
