TypedDict in 3.8 gives unexpected error?

[IanVermes]

@rchen152 Forgive me for the naive question, but am I correct that TypedDict support from the typing module is not supported by PyType (as of version 2021.02.09 while running against Python 3.8)? Issue #680 corroborates this but the error message I get is unclear.

I get an import-error rather than a not supported error, which is confusing me. Equally I may be doing something utterly wrong!

I get the following

$ pytype -V 3.8
...
Can't find module 'typing.TypedDict'. [import-error]

# some_file.py
from typing import TypedDict

Keywords = TypedDict(
    "Keywords",
    {
        "foo": str,
        "bar": str,
        "bat": bool,
    },
)

Yeah, we should be reporting [not-supported-yet], not [import-error]. To fix this, we'd need to add a definition for TypedDict to https://github.com/google/pytype/blob/master/pytype/stubs/builtins/2and3/typing.pytd and a not_supported_yet entry in

pytype/pytype/overlays/typing_overlay.py
