I would prefer not to include code that isn't being used (even if it's commented out), especially if it doesn't come with a test. This method has a typo. It's expecting a parameter `data`, but you're not using it in the method. Instead, you're using an instance variable `@data` which hasn't been defined. The fix is to replace `@data` with `data`, but this method should come with a test before we include it.
