In this paper we show that this approach can also be used to integrate different language paradigms into a unified framework. Furthermore, we study the syntactic, semantic and operational impacts of this idea for the amalgamation of declarative and constraint programming.30 pages, 9 figures, To appear in Theory and Practice of Logic Programming (TPLP)Programming LanguagesArtificial IntelligenceD.3.2text
