Abstract

The obliviousness property of AspectJ conflicts with the ability to reason about an AspectJ program in a modular fashion. This makes debugging and maintenance difficult. In object-oriented programming, the discipline of behavioral subtyping allows one to reason about programs modularly, despite the somewhat oblivious nature of dynamic binding; however, it is not clear what discipline would help AspectJ programmers obtain modular reasoning. We describe this problem in detail, and sketch a solution that allows programmers to tell both ``superimposition'' and ``evolution'' stories in their AspectJ programs.
