   Thanks for the report! This notice comes from Symfony's DebugClassLoader rather than PHP itself. We already mark the method with #[\ReturnTypeWillChange], but Symfony also looks for a plain @return annotation, and we only had @phpstan-return.

   We can't add a native mixed return type in 2.x because mixed requires PHP 8.0 and this version still supports PHP 7.4. Instead, we've added an explicit @return annotation in #1161, which silences the notice and will be included in the next 2.x release. The native type can come in 3.0 once PHP 7.4 support is dropped.

   Great! Thank You.

   I have just one more question: Why do You use @phpstan-* annotation instead of direct PHP-Doc ?

   Before:

   /**
    * @phpstan-template T
    * @phpstan-implements \IteratorAggregate<int, T>
    * @phpstan-implements \ArrayAccess<int, T>
    */
   final class ArrayCollection implements \IteratorAggregate, \Countable, \ArrayAccess
   {
      /**
       * @var array<int, mixed>
       * @phpstan-var array<int, T>
       */
       private array $elements;
   
       //...
   }

   After:

   /**
    * @template T
    * @implements \IteratorAggregate<int, T>
    * @implements \ArrayAccess<int, T>
    */
   final class ArrayCollection implements \IteratorAggregate, \Countable, \ArrayAccess
   {
       /**
        * @var array<int, T>
        */
       private array $elements;
   
       //...
   }
