Description:
------------
Playing around with PHP 8, I found something in Union Type's error messages, specific in typed arguments: the types are report in a different position from where they were declared.

Test script:
---------------
<?php

class ValidMagicMethods {
	public function myMethod(string $name, array $arguments): mixed {}
}

final class NarrowedReturnType extends ValidMagicMethods {
	public function myMethod(string|array $name, bool $arguments): string|float|null {}
}

Expected result:
----------------
Fatal error: Declaration of NarrowedReturnType::myMethod(array|string $name, bool $arguments): string|float|null must be compatible with ValidMagicMethods::myMethod(string $name, array $arguments): mixed in /in/WE96o on line 8


Actual result:
--------------
Fatal error: Declaration of NarrowedReturnType::myMethod(string|array $name, bool $arguments): string|float|null must be compatible with ValidMagicMethods::myMethod(string $name, array $arguments): mixed in /in/WE96o on line 8
