GPB has done an initial review and left a comment https://github.com/php/php-src/pull/6921#pullrequestreview-646848902 in which he suggests I open this up to the floor, so here it is, seeking your feedback kindly. Also if anyone can clarify what is meant by a warning "will be promoted in PHP 9", I am not familiar with what changes are planned for the next major version? Regards DavidHey David, What I meant is that we usually don't introduce an exception without prior warning to existing functionality. So making this a Warning in the PHP 8 series which gets promoted to a TypeError in PHP 9, similarly to how most of the internal functions went from returning null + warning to throwing a TypeError, or many of the warnings that got promoted to ValueErrors in 8.0 because it's a major release. Personally I don't mind introducing the TypeError immediately in PHP 8.1, because compact() should be rather rare and mostly used on an array, but others might feel differently about this. Best regards, George P. Banyard
Does anyone have any thoughts or concerns about this being in 8.1? I'm trying to decide whether to merge the PR, and I'd like to make sure anyone who wants to speak up has a chance to do so.
Cheers, Ben
