Incrementing Characters in Perl

I've got a function I'm converting from C to Perl.  One of the things I do
is add to letters, so for instance my C code is
char letter;

letter = 'A';
letter += 3;

which would make letter 'D'.  

In Perl this doesn't work
$letter = 'A';
print $letter , "\n";
$letter = $letter + 4;
print $letter , "\n";

prints 'A' , '4'

Using chr and Ord I found a way to make it work.  

$letter = 'A';
print $letter , "\n";
$letter = chr(ord($letter) + 4);
print $letter , "\n";

But I was wondering if you could think of anything slicker, using regex, tr,
or something like that.  No big deal as I do have a solution.  Just
wondering if there is a better way to do it.
