Hello PHP,
I just started the vote on
https://wiki.php.net/rfc/normalize-array-auto-increment-on-copy-on-write
and I will close it in one week from now
From the discussion (https://externals.io/message/105992) it emerged the
intention to make the proposed change even stricter.
But, given that's a way bigger problem and difficulty, I decided to proceed
with this anyway for now, because it's compatible with future improvements,
and because fixes the most dangerous inconsistencies currently observable,
that is, arrays passed to third parties with unpredictable auto-increment
values.
Thank you for reading and for voting
