That’s basically my thoughts on this RFC.

Yeah, that’s the problem. It is somewhat unclear, but any other keyword choice is even more confusing. I discussed this quite a bit in StackOverflow’s PHP chatroom (http://chat.stackoverflow.com/rooms/11/php) and couldn’t come up with anything better. Also, as I note in the RFC, we already use readonly in the docs for some classes, and for C#-style only-set-once read-only properties, we could use final or immutable. -- Andrea Faulds http://ajf.me/
