The nesting level of this method is pretty deep. You can flatten it by using early exits.    ```php  foreach ($metadataBundle['alias']['territory'] as $alias => $data) {      if (3 !== \\strlen($alias) || 'overlong' !== $data['reason'] || ctype_digit($alias)) {          continue;      }        $alpha2Code = $data['replacement'];      if (!isset($alpha2Codes[$alpha2Code])) {          continue;      }      // \u2026  ```
