Yes, I am aware that generics are being worked on. However, generics wouldn't
provide structural interfaces for arrays. 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
```
