I would opt to the same behaviour as ['foo' => 1] + ['foo' => 2] // where 'foo' key results in 1 But maybe this should be optional voting for that, either way, we're delivering feature which has very limited usage which can be confusing, cause I can array_merge or use + operator so why can't I use keys with spread operator if I already have them in my generator, iterable or array which came from for eg. json_decode or whatever. -- regards / pozdrawiam, -- Michał Brzuchalski about.me/brzuchal brzuchalski.com
