For PHP 6, we could probably make a 2to3-style tool (2to3 is a utility for converting Python 2 to Python 3 source code) for converting from PHP 5 to PHP 6. Nikic’s PhpParser would be useful for this, and he’s already made a tool to help spot things this RFC would break. -- Andrea Faulds http://ajf.me/
