Abstract
Refactoring, in spite of widely acknowledged as one of the best practices of object-oriented design and programming, still lacks quantitative grounds and efficient tools for tasks such as detecting smells, choosing the most appropriate refactoring or validating the goodness of changes. This is a proposal for a method, supported by a tool, for cross-paradigm refactoring (e.g. from OOP to AOP), based on paradigm and formalism-independent modularity assessment.
