Confusion in what is a collection for OkContent response

[Nek-]

Example of the problem:

class MyController
{
    public function __invoke(ItemProvider $provider)
    {
        $items = array_filter($provider->getItems(), function ($item) {
            return $item->isPublic();
        });
        return new OkContent($items);
    }
}

The result will be miss-formatted collection. The reason is that the OkContent normalizer use the array as direct result. (which makes sense since we should be able to return "single object" as a form of array)

Here are 2 potential solutions, vote on the issue if you feel concerned with ❤️ or 🎉 for the second.

First solution ❤️

Adding a new method setCollection(true) to the OkContent response.

The previous code would look like that:

$response = new OkContent($items);
$response->setCollection(true);
return $response;

Second solution 🎉

Adding a new class "collection" to Melodiia. The previous code would look like that:

return new OkContent(new Collection($items));

WDYT?

I'm in favor of the first one, considering we can already use new OkContent(new ArrayIterator($items)).
