Is there a way to select multiple values from the array without repetition? For instance how to properly do the following: 
my @arr = ('A'..'Z');
my $random_letter1 = $arr[int rand @arr];
my $random_letter2 = $arr[int rand @arr];
my $combo = $random_letter1 . $random_letter2;
print $combo . "\n";

Is there a way to do selection of both values in one line instead of adding up random_letter1, 2 and so on?
