If you have to work with lists of ISO 3166-1 alpha-2 country codes that sometimes include fake codes that should be expanded to a longer list, e.g. 'EU', or if you have to deal with lists of territory metadata like 'EU -FR' then territorial will help. It defines some commonly seen default expansion codes, and allows you to correctly expand a string like 'EU -FR' into an array of 2-letter country codes
