A reflective extension of ELAN

The expressivity of rewriting logic as meta-logic has been already convincingly illustrated. The goal of this paper is to explore the reflective capabilities of ELAN, a language based on the concepts of computational systems and rewriting logic. We define a universal theory for the class of ELAN programs and the representation function associated to this universal theory. Then we detail the effective transformations to implement and propose the definition of two built-in modules that provide the last step to get the reflective capabilities we want for the ELAN system.
