A distinctive feature of modern functional logic languages like Toy or Curry is the possibility of programming non-strict and non-deterministic functions with call-time choice semantics. For almost ten years the CRWL framework [6,7] has been the only formal setting covering all these semantic aspects. But recently [1] an alternative proposal has appeared, focusing more on operational aspects. In this work we investigate the relation between both approaches, which is far from being obvious due… CONTINUE READING
