I like this approach, too; the hash makes exceptions to the "uppercase bracket" basic rule perfectly clear. However, I also agree with other posters (1) treating $country as a temporary variable isn't great practice, and (2) it's not entirely clear what $card->country is allowed to return. Given those concerns, my own preference would be
my %exceptions = ('' => '', gbr => ''); my $c = $card->country || ''; my $country = exists($exceptions{$c}) ? $exceptions{$c} : uc "[$c]";
