Castables don't work when used from a constructor

[savr-reda]

Hi everyone, I am using the latest 3.2.1 version of the package with Laravel 10 and PHP 8.2. As an example, I used the sample provided in the documentation:

class ForgotPasswordRequest extends Data
    public function __construct(
        #[WithCastable(Email::class)]
        public Email $email,
    ) {}
}

class Email implements Castable
{
  public function __construct(public string $email)
  {
  }

  public static function dataCastUsing(...$arguments)
  {
    return new class implements Cast
    {
        public function cast(DataProperty $property, mixed $value, array $context): Email
        {
            return new Email($value);
        }
    };
  }
}

When I try to create the request via the constructor, I get a type error message:

$forgotPasswordRequest = new ForgotPasswordRequest('[email protected]');

TypeError: ForgotPasswordRequest::__construct(): Argument #1 ($email) must be of type Email, string given

However, it works as expected when using the from method:

$forgotPasswordRequest = ForgotPasswordRequest::from(['email' => '[email protected]']);

Since the documentation is not explicit enough about that part, is that supposed to be an issue or the intended behavior?

This is expected behavior, we cannot overwrite this stuff since it is not possible in PHP

Hi @rubenvanassche, glad it got confirmed then. Thank you for your answer!
