Estimated hours taken: 1.2 Branches: main In the declarative debugger: use predmode syntax where appropriate; use `.' as a module qualifier instead of `__'; use state variables for IO instead of DCGs; use `io' instead of `io.state'. browser/declarative_debugger.m browser/declarative_execution.m browser/declarative_oracle.m browser/declarative_test.m browser/declarative_tree.m browser/declarative_user.m Apply the above mentioned changes.
