[development] Call time pass-by-reference for PHP 5.4

What is going to be the best way to handle the removal of call time pass-by-reference as noted at http://www.php.net/manual/en/migration54.incompatible.php? This affects a lot of code. Based on http://drupal.org/node/1498574 D8 will not be ready for PHP 5.4 but some WAMP and LAMP are already delivering it. My query here though is more looking at preparing for any new modules or converting older modules and getting them ready for PHP 5.4. How do others plan to handle this offensive change? -- Earnie -- https://sites.google.com/site/earnieboyd
