        my @animals = qw(dog cat fish parrot hamster);
        my @sorted = reverse sort @animals;
        print "I have the following pets: @sorted\n";

        my $word = "backwards";
        my $mirror = reverse $word;
        print qq("$word" reversed is "$mirror"\n);

        %by_address = reverse %by_name;	 # Beware of lost duplicate values
