ObjectId seems not to be properly typed

[alebg]

Hi guys!

I'm using your library in my project. I have a very strict typing setup, with poetry and python 3.13, and mypy complains about certain things. Using the latest (5.10) version of bson .

Context

...
[tool.poetry.dependencies]
python = "^3.13"

...

[tool.poetry.group.mongo.dependencies]
pymongo = "^4.11.3"
bson = "^0.5.10"
mongoengine = "^0.29.1"

[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"

[tool.mypy]
python_version = "3.13"
strict = true
ignore_missing_imports = true
plugins = ["pydantic.mypy"]
explicit_package_bases = true
exclude = [
  "tests/types",
]

Issues

1. More of a question, but could point to an issue:

from bson import ObjectId

Yields the typing error:
Module "bson" does not explicitly export attribute "ObjectId"

Which gets fixed by doing:

from bson.objectid import ObjectId

Does this make sense as a solution on my side? both seem to point to the same place

2. Independently of that, doing a simple:

value = ObjectId(<anything>)

Yields the typing error:
Call to untyped function "ObjectId" in typed context

The issue seems to come from this line not being properly typed:

bson/bson/objectid.py

Line 85 in 5a85a1c

def __init__(self, oid=None):

A possible fix:

def __init__(self, oid: Any = None) -> None:

Thanks a lot! Let me know if this makes sense, or if you need more details
