[tpm] Greedy regex question

Hi all,

   Given the string:

$val="0  (0x0)  (int)";

   Why does:


   Properly, ungreedily, return "0    (int)" *but*, changing it to:


   Wrongly, greedily, return "0  "? When I put the '.*?' in brackets and 
print '$1' on the later it is indeed grabbing "0x0)  (int".

   What is it about anchoring the regex to the end of the string cause 
it to be a greedy regex again? As you can probably gather, I am trying 
to get rid of /only/ the last '(foo)' in a given string.
