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.
