Relevant older questions:

• Class properties in Python 3.11+
• What are some similar alternatives to using classmethod and property decorators together?

Out of all of them, the following answer was most appealing to me. A small rewrite + example (I am using Python 3.12+):

from functools import update_wrapper
from typing import Callable


class classprop[T]:
    def __init__(self, method: Callable[..., T]):
        self.method = method
        update_wrapper(self, method)

    def __get__(self, obj, cls=None) -> T:
        if cls is None:
            cls = type(obj)
        return self.method(cls)


class MyClass:
    @classprop
    def hello(self) -> str:
        return "world"


x = MyClass()
x.hello

This raises a type error (silenced in the original answer):

Argument of type "Self@classprop[T@classprop]" cannot be assigned to 
parameter "wrapper" of type "(**_PWrapper@update_wrapper) -> _RWrapper@update_wrapper" 
in function "update_wrapper"
  Type "Self@classprop[T@classprop]" is incompatible with 
  type "(**_PWrapper@update_wrapper) -> _RWrapper@update_wrapper"

Is there a way to address this type error, instead of silencing it? (i.e. is it raising a valid concern?) What is the error even saying?
