I've started to work on the RFC document to collect some of the information we've discussed in this thread. I do not have the ability to edit wiki.php.net, so I cannot put the RFC on there at the moment. In lieu of that, I've created a placeholder markdown document on github for the RFC page: https://github.com/JordanRL/operator-overloading-rfc/ This is not where I will work on the implementation (which will obviously be on a fork of php-src). I've outlined my rough idea of the implementation I'm leaning towards in this doc, but have left out any discussion about interfaces for now, as I feel that's something that could use further discussion. Any feedback would be appreciated at this early stage. Jordan
