Abstract

The obliviousness property of AspectJ-like languages conflicts with the ability to reason about programs in a modular fashion. This can make debugging and maintenance difficult. In object-oriented programming, the discipline of behavioral subtyping allows one to reason about programs modularly, despite the oblivious nature of dynamic binding; however, it is not clear what discipline would help programmers in AspectJ-like languages obtain modular reasoning. Behavioral subtyping was born out of the stories programmers were telling in their object-oriented programs and how they reasoned about them. Programmers use AspectJ-like languages to tell what we call ``superimposition'' and ``adaptation'' stories. Thus, a discipline of modular reasoning for an AspectJ-like language must account for both sorts of stories. We describe the modular reasoning problem for AspectJ-like languages. We do not yet have a solution, but concisely articulate the issues involved.
