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

[Earnie Boyd]

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?
