As the RFC and discussion note, the design space here overlaps significantly with both readonly/immutability and property accessors. We should take enough time to consider these alternatives/extensions as well, to ensure that we don't end up with multiple distinct and possibly incompatible mechanisms. We don't have that time before PHP 8.0 feature freeze. Regards, Nikita
