Symfony version(s) affected

6.4.2 (Other versions most likely as well)

Description

For some reason the serializer doesn't seem to like variadic arguments in the constructor

How to reproduce

When deserializing a json object like this

{
    "requiredParameter": "required",
    "optionalParameter": "optional",
    "variadicParameter": [
        {"param": 1},
        {"param": 2}
    ]
}

into a PHP class like this

class ChildExample {
    public function __construct(
        private int $param,
    ) {}
}

class Example {
    private array $variadicProperty;

    public function __construct(
        private string $requiredParameter,
        private string $optionalParameter = '',
        SomeClass ...$variadicParameter,
    ) {
        $this->variadicProperty = $variadicParameter;
    }
}

I get the PHP error Error : Cannot use positional argument after named argument on line 429 of AbstractNormalizer.php.

Possible Solution

When I wrap the $params variable in an array_values() call the problem goes away. I'll try to create a pull request with my fix later.
