Desfuncionalizar para Provar
share
This paper explores the idea of using defunctionalization as a proof technique for higher-order programs. Defunctionalization builds on substituting functional values by a first-order representation. Thus, its interest is that one can use an existing program verification tool, without further extensions in order to support higher-order. This papers illustrates and discusses this approach by means of several running examples, built and verified using the Why3 verification framework.
