| # Ensuring these errors are emitted correctly in all relevant cases |
| # meant moving to a more systematic test structure that allows the |
| # test structure to map more directly to the module structure |

| # Note that if the constructors are refactored so that addresses with |
| # multiple problems get classified differently, that's OK - just |

| # test suite and the new systematic tests. While some redundancy in |
| # testing is considered preferable to accidentally deleting a valid |
| # test, the original test suite will likely be reduced over time as |
