Please either open a PR or open an issue that describes any work that is in progress, that you would like to have some other people help with.
It is also possible to suggest some ideas that could be worked on. However I'm not going to list every possible piece of work; I'm only going to list things that either people have already started themselves, or a really obviously good thing.
As otherwise there is an infinite amount of things that could be worked on.
If you have link to useful info about PHP internals, please suggest it as a PR or issue.
The RFC Codex that describes previous RFC discsussions is going to be more restricted in what information is added.
The following things would be appropriate to contribute and will be well received.
If you can think of a topic that comes up on internals regularly that isn't already documented here, please either suggest it, or even better, write a document for it.
If one of the topics listed has another problem with it that has been missed, that would need to be overcome before the topic could be progressed.
Speeling is hard.
The following things are not appropriate to contribute, and won't be well received here.
This documentation isn't to stop ideas....it's to make people aware of what the challenges are for certain ideas, so that we can avoid having people thinking that 'those internals people' haven't considered X, and to avoid the same discussions over and over.
If you have a cunning plan to make one of these 'blocked' RFCs happen, I'd suggest either discussing it with me on Twitter or the PHP chat room on Stackoverflow.
This repo is just for documenting the problems RFC face.
