Re: Invokation on __toString() for object used as array key

Hi, Joe Watkins wrote (for fun) a new operator, addressof. Code is here: https://github.com/krakjoe/php-src/compare/addressof I think it makes more sense than a new method on all objects. You could use it for any kind of value: scalar, resource, object. Building an array of sockets, for example, would be very easy with such an operator. It would also give better tools to deal with situations such as: $test = 1; $test2 &= $test; I'm willing to write an RFC if necessary to include it. Thoughts?
