New submission from jhwang <joengmin at gmail.com>:

I have Python 3.10.1 (Dec, 2021) installed and I see an error when inspecting signature of TypedDict class. This is the same issue reported on Issue43006 (msg385535 - (view)). It was marked as resolved but the error looks persistent. Can someone confirm if this was fixed or any release version with the fix? 

    import inspect

    class T(typing.TypedDict):
        a: int


was `(*args, **kwargs)` and now raises `ValueError: no signature found for builtin type <class 'dict'>`
