That looks a bit less readable to me, would it be better to change to this?
```
 if (IsNewFormat != IsNewDbgInfoFormat) {
        if (IsNewFormat) {
            convertToNewDebugFormat();
        } else {
            convertFromNewDebugFormat();
        }
     IsNewDbgInfoFormat = IsNewFormat;
   }
```
 `IsNewDbgInfoFormat = IsNewFormat;` // would be nice 
 We can then refactor/remove the `IsNewDbgInfoFormat = true/false` from `convertToNewDebugFormat()` and  `convertFromNewDbgValues()` and just keep this line in `setIsNewDbgInfoFormat` and then the method name also makes a bit more sense in terms of really "setting" the new debug format 😉
