Curses screens, windows and pads are typed as curses.window, and the widgets that may get no parent window take curses.window | None. - EventHandler is generic over a ParamSpec, so each handler declares the arguments it passes, and MenuView is generic over the item its on_confirm hands out. Choice callbacks take no arguments. - Scrollable is generic over its items, which DataTable and ListBox fix to tuple[str, str] and str. - random.choice() and choice_low() are generic over the sequence, so the casts at their call sites are gone. BasicUserInterface.menu() and util.first() are generic too. - Signal callbacks and their payloads are Callable[..., object] and object, since emit() only forwards them. - JSON values in game_data are object and narrowed by isinstance, and data files are Traversable. - Signal handlers take an int and a FrameType | None, and list_players() takes a TextIO. - The focus_standout() context managers return Generator[None, None, None]. Any remains in three places: Player.__setstate__, whose pickled __dict__ holds values of every type; Focusable.__init__, a mixin that passes *args and **kwargs through to the next class; and the values load_game_data() collects, whose element type depends on the field each one fills.
