[RFC] [Re-proposed] Adopt Code of Conduct

Hi, I've decided to re-propose the CoC RFC. There are many reasons for it, but there are a few points I want to make. I strongly believe that a Code of Conduct is required. The amount of toxic behaviour on this list is in my opinion unacceptable. It drives people away, it certainly did. It is also one of the reasons I am not nearly as active as I used to be. It also makes me reluctant to welcome and mentor new people wanting to contribute. I have said "no" to two people in the last few days, mostly because I am not sure whether I want them exposed to some of the things being said on the list. But I think this list, and hence this project, and language, can be improved. A Code of Conduct alone is not enough. The focus for this list, and wider community, should be on collaborating to make PHP even better and faster than it already is. Collaboration works better in a happy environment, where people work together instead of against eachother. The new 0.5 version of the RFC that is up at https://wiki.php.net/rfc/adopt-code-of-conduct focusses more on working together and mediation than on acting with an iron fist on when things go awry, although these parts of the RFC are still included. In my opinion, an CoC that is not enforced is nothing but some text on a piece of paper—or in our case, a few bits on a disk. I have added a section, Constructive Contributor Guidelines, in addition to the CoC. This section definitely needs improving. I would everybody invite you to help out improving this RFC, but please take into account https://wiki.php.net/rfc/adopt-code-of-conduct#constructive_collaboration_guidelines I want this to work, and work together, to get this approved. cheers, Derick
