Yes, increment is magic, but decrement is not. In the perlop man page
(perldoc perlop), you'll find
Auto-increment and A

Hello everybody
Incrementing and decrementing strings are quiet puzzling to me. I don't seem
to figure out the rationale behind the use of the increment (++) and decrement
(--) operators when it comes to strings. Let me illustrate:
$str = 'hello';
$str++;
print "$str\n"; # here we get "hellp".
