Support for collection map

[rforced]

I have the following being returned as a response

        return response()->json([
            'thoughts' => $thoughts->map(function (Thought $thought) {
                return [
                    'id' => $thought->id,
                    'name' => $thought->name,
                    'owner' => [
                        'name' => $thought->owner->name
                    ],
                    'size' => $thought->size,
                ];
            })]);

Scramble doesn't appear to detect this and instead shows a "string" return type for "thoughts".

How would one properly document this response for scramble?
