NotSet is unknown import symbol

[ocket8888]

Checking this code:

from github.GithubObject import NotSet

with Pyright version 1.1.225 fails with the error "NotSet" is unknown import symbol.

The definition of NotSet from GithubObject.py is

class _NotSetType:
    def __repr__(self):
        return "NotSet"

    value = None


NotSet = _NotSetType()

A typing that would fix this unknown import problem is

from typing import Final

class _NotSetType:
    def __repr__(self):
        return "NotSet"

    value = None


NotSet:  Final = _NotSetType()

However, that doesn't allow me to use NotSet as a type, like:

from typing import Union
from github.GithubObject import NotSet

def print_something(a: Union[str, NotSet]) -> None:
    if a is NotSet:
        print(a.value)
    else:
        print(a)

Which fails with the error Expected class type but received "_NotSetType".
