array_reject() as counterpart of array_filter()

Currently we have array_filter(), but sometimes we need an inverse function like array_reject(). array_reject('is_null', [ 1, 2, null, 3 ]); // [ 1, 2, 3 ] It could be easily implemented with: function array_reverse($fn, $arr) { return array_filter(fn($item) => !$fn($item), $arr); } Anyway, I think that It should be implemented by core, once that we have array_filter().
