The optional feature problem in feature-oriented programming is that implementing the interaction among features is difficult. Either of the modules for the interacting features cannot contain the code for the interaction if those features are optional. A modular approach for implementing such interaction is separating it into a module called derivative. However, as the number of derivatives increases, it does not scale. This paper shows how derivatives for combinations of features from each group are efficiently implemented. A group of features are implemented by using the inheritance of feature modules. A super feature module works as a common interface to members of that group. It thereby allows to describe a generic derivative applicable for the groups. This paper also presents a feature-oriented programming language, FeatureGluonJ, which provides language constructs for this approach.
