    LUP does not derive unsat?

    Or LUP does not derive unsat for infinite domain?

    If I'm not mistaken, applying propagation to structure will not finish as soon as the structure is inconsistent, which might be a possible optimisation...

    It does not stop soon enough (after the first inconsistent element is added). But in this case, couldn't we even stop before generating any elements?
