At most it would provide a way to infer/define generic types for array keys and/or values. I guess I should've provided a code example straight away. Here's what I have in mind: ```php declare(strict_types=1); shape MyArray { "id": int; "name": string; } function doArrayStuff(MyArray $array) { ... } doArrayStuff(['id' => 1, 'name' => 'Alwin']); // Works, array conforms to shape doArrayStuff(['id' => '1', 'name' => 'Alwin']); // Fails, 'id' should be int ``` The best that Generics would be able to offer for arrays is: ```php function doArrayStuff(array<string, int|string> $array) { ... } doArrayStuff(['id' => 1, 'name' => 'Alwin']); // Works doArrayStuff(['id' => '1', 'name' => 'Alwin']); // Works ``` Alwin
