So far the two didn’t go together and we had to use a cludge. With the upcoming release we provide a proper solution based on marking write-barriers. Our remembered set on the variable binding trail has the benefit that it can reduce itself during backtracking. By adopting conductor variables, i.e. instantiated variables that are not trailed, from formerly Jekejeke Prolog, we could recreate a similar benefit for Dogelog Players change_arg/3.
