+This includes:
+- Extra comments that a human wouldn't add or is inconsistent with the rest of the file
+- Extra defensive checks or try/catch blocks that are abnormal for that area of the codebase (especially if called by trusted / validated codepaths)
+- Casts to any to get around type issues
+- Any other style that is inconsistent with the file
