I found these snippets:
https://psalm.dev/r/b46281057c
<?php
final class MyClass
{
private \stdClass $config;
public function __construct(\stdClass $config) {
$this->config = &$config;
}
}
Psalm output (using commit 08afc45):
INFO: UnusedClass - 3:13 - Class MyClass is never used
INFO: UnusedParam - 7:43 - Param #1 is never referenced in this method
from psalm.
Object are always passed by reference. $this->config = &$config;
is the exact same as $this->config = $config;
It saying the param is unused is a bug, but you can avoid it by not having redundant code.
Here is an example of this bug with non-redundant code: https://psalm.dev/r/578763b870
from psalm.
