Interesting case. Might actually be a bug, despite the __get + by-ref assignment combination. After
all, uninitialized typed properties are not supposed to trigger magic methods, so the existence of
__get should be immaterial here...

Description:
------------
Test script leads to fatal error when magic method __get() is declared and assign by reference.
Test script:
---------------
<?php
final class A
{
public string $a;
public static function fromArray(array $props): self
{
$me = new static;
foreach ($props as $k => &$v) {
$me->{$k} = &$v; # try to remove &
}
return $me;
}
public function __get($name)
{
throw new \LogicException("Property '$name' is not defined.");
}
}
A::fromArray(['a' => 'foo']);
Expected result:
----------------
(no error)
Actual result:
--------------
Fatal error: Uncaught Error: Typed property A::$a must not be accessed before initialization.
