[rfc] pow operator voting ended

Hi internals, The voting period has ended; a right associative power operator is voted in for inclusion for PHP 5.6. Depending on how you look at the "non associative" option, the tally is: * 23 / 32 (71%) according to the rules stated under the #vote section * 22 / 31 (70%) as abstained vote * 22 / 32 (68%) as against vote In all above cases, there's a two third majority. I would like to thank you all for the feedback and votes. -- -- Tjerk
