Maybe not the best solution, but you can create a language HoH that contains the translations for different languages. For example:

my $languages = {
   english => {
      not_found => 'File not found',
   },
   german => {
      not_found => 'File nichte founden',
   },
 }

Then in your application you can set the default language like so:

my $language = $languages->{german};
print $language->{not_found};
