I was preparing a different post and managed to cause the language server to crash loop ....
In a new window, create an unsaved document and enter:
<?php
/**
* @template T
*/
abstract class Parent {
/** @param T $arg */
abstract function do_thing($arg): void;
}
/** @extends Parent<int> */
class Child extends Parent {
}
