N2 - An aspect encapsulates not only crosscutting behavior, but also crosscutting state. When aspects are stateful, there is a need to specify and control their instantiation. Unfortunately, aspect instantiation is a hard-wired feature in AspectJ. This feature cannot be customized by the application programmer. Specifically, there are six pre-defined instantiation models to choose from, each designated by a keyword: issingleton, perthis, pertarget, percflow, percflowbelow, pertypewithin. In this work, we introduce a new language mechanism and keyword 'perscope' that lets third-parties define custom aspect instantiation models. This new keyword replaces the six existing keywords in AspectJ, and may eliminate the need for introducing future ones.
