There are a few questions that come to mind (there may be more). * Are integer keys preserved? I'm assuming no, as otherwise it would be the same as `$a + $b`. * What is the return value of the expression `$a[...] = $b`? I'm assuming $a after the additions of $b? * How does it behave in combination with `ArrayAccess`? Throw? Call `offsetSet` for each element? * How does it interact with references? E.g. This is valid PHP code: `assign_by_ref($a[])` (https://3v4l.org/qoJYn) * How does it interact with undefined/null values? E.g. `$a[] = 42;` works without declaring $a first. * Is there a need for this? Given that `+` doesn't work with sequential lists and `array_push($a, ...$b)` doesn't work with strings I'd say possibly. `[...$a, ...$b]` works but requires duplication of the array which in loops can be detrimental to performance.
