How to use formats in DateTime :: Locale with a DateTime object?

DateTime :: Locale contains a very detailed list of date and time formats for different regions and countries. I would like to use it in emails for clients, depending on what country the client is in.

Unfortunately, it’s very difficult to understand from the documentation how to actually use functions for medium or long dates. For example, DateTime :: Locale :: de_DE lists these date formats (excerpts) in a document:

Long
 2008-02-05T18:30:30 = 5. Februar 2008
 1995-12-22T09:05:02 = 22. Dezember 1995
-0010-09-15T04:44:23 = 15. September -10

Medium
 2008-02-05T18:30:30 = 05.02.2008
 1995-12-22T09:05:02 = 22.12.1995
 -0010-09-15T04:44:23 = 15.09.-010

It's great. According to DateTime :: Locale :: Base, there are methods in the locale object to get these formats: $locale->date_format_long()and $locale->date_format_medium().

my $locale = DateTime::Locale->load('de_DE');
