I was expecting no error as the parameter name is $info which is exactly what it should be. https://www.php.net/manual/en/splobjectstorage.attach.php Where is $data coming from?

I found these snippets:

<?php

class A extends SplObjectStorage {
 public function attach(object $object, mixed $info = array()): void {}   
}

Psalm output (using commit 03ee02c):

ERROR: MissingTemplateParam - 3:7 - A has missing template params when extending SplObjectStorage, expecting 2

ERROR: ParamNameMismatch - 4:47 - Argument 2 of A::attach has wrong name $info, expecting $data as defined by SplObjectStorage::attach
