Simple Crosscutting Concerns Are Not So Simple: Analysing Variability in Large-Scale Idioms-Based Implementations

This paper describes a method for studying idioms-based implementations of crosscutting concerns, and our experiences with it in the context of a real-world, large-scale embedded software system. In particular, we analyse a seemingly simple concern, tracing, and show that it exhibits significant variability, despite the use of a prescribed idiom...
