since a recent change we have

if (!$node instanceof Node\Expr\MethodCall && ! $node instanceof Node\Expr\StaticCall) {
			return [];
}

at the very top of this rule, therefore we don't need to narrow here again anymore.

$node->name = new Node\Identifier($correctName);
}

if ($node instanceof Node\Expr\StaticCall) {
$node->name = new Node\Identifier($correctName);
}
$node->name = new Node\Identifier($correctName);

return $node;
})

Pretty sure you're breaking the args list contract here 😊

good point.

what do you think about moving the new PHPParser stubs into the regular phpstan-src stubs/ directory and load them conditional via a new phpstan-src config parameter, so we can enable the more precise types in 1st party extension repos.

@staabm I'm not sure about it. I don't feel like adding a configuration option and documenting it is justified just as a temporary measure before your PR on PHP-Parser is merged.
