Is there a way to hint that a function is abstract and doesn't need a body, like with the P = ParamSpec('P')
T_co = TypeVar('T_co', covariant=True)
class TypedSignal(Generic[P, T_co]):
def __init__(self, spec: Callable[P, T_co]) -> None: ...
def connect(self, handler: Callable[P, T_co]) -> Callable[P, T_co]: ...
def send(self, *args: P.args, **kwargs: P.kwargs) -> list[tuple[Callable[P, T_co], T_co]]: ...
@TypedSignal
def my_signal(sender: SomeType, arg: OtherType) -> ReturnType: ...
@my_signal.connect
def my_signal_handler(sender: SomeType, arg: OtherType) -> ReturnType:
