Possibly also __destruct(), __sleep(), __wakeup(), and __clone().

__construct() only needs documentation of its parameters, if there aren't any there's probably nothing worth documenting there.

__call(), __callStatic(), __get(), __set(), __isset(), __unset(), __invoke(), and __set_state() probably do want documentation as to what exactly they're doing.

Agreed. Created a parent task.
