[RFC] Readonly properties

Hi internals, I'd like to open the discussion on readonly properties: https://wiki.php.net/rfc/readonly_properties_v2 This proposal is similar to the https://wiki.php.net/rfc/write_once_properties RFC that has been declined previously. One significant difference is that the new RFC limits the scope of initializing assignments. I think a key mistake of the previous RFC was the confusing "write-once" framing, which is both technically correct and quite irrelevant. Please see the rationale section ( https://wiki.php.net/rfc/readonly_properties_v2#rationale) for how this proposal relates to other RFCs and alternatives. Regards, Nikita
