Hi nikic,
https://3v4l.org/nkocf is different example than what is have.
Using a pointer will work(there's no warning for that until 7.4.0). See https://3v4l.org/H5SPf.

Worth noting that this warning is actually very old (dating back all the way to PHP 5.0: https://3v4l.org/nkocf). PHP 7.4 fixed a special case where the
warning was missing (references as opposed to direct writes) and PHP 8.0 removed this functionality
completely.
Note that auto-vivification is still supported for arrays (and I don't believe there are plans
to remove it there).

This is project personal I started more three years ago, so it's no big deal for me. I just
revert back to PHP7. I only wanted to checkout the performance improvements.
Even though, it's unlike to be reverted, I would like to add this issue to the internals
mailing list. I don't see why making more things more restrictive is an improvement. How do I
bring it up to the internals mailing list?

I don't think so. If you strongly feel that this "feature" should
not have been disallowed, please raise that on the internals
mailing list, although I consider it unlikely that the change will
be reverted.
> there is a reason to introduce warnings years before
In this case it has been only *one* year.

Thanks for the quick response. I was upgrading from PHP7.0 so didn't get any warnings. By
crash, I meant the my script was crashing.
So, is there any work around other than explicitly instantiating each variable. This seems like a
big inconvenience, special if one relied this behavior for API development.
