Hi internals, Based on the feedback on the original RFC targeting 7.2, I have now updated the RFC to target version 8.0. Additionally, I changed the existing PR to throw a E_DEPRECATED notice on the cases where this RFC will cause a BC break when the change is implemented to ease the detection of such cases.
I have closed the current vote (YES 14 - 16 NO) and opened a new one for the revised RFC targeting the next major version. You can vote (again) at https://wiki.php.net/rfc/negative_array_index until 28/6/2017 19:00 UTC. Regards, Pedro
