The actual implementation is performed by type checkers like mypy. We just need to add `TypedDict` to the `typing` module.

Either 135c6a56e55d2f4f8718b3b9f03ce3c692b15f0f or b891c465bb7d38a597c5c2ad547d7b19194f4dad (#37046) broke the build. Lib/test/test_typing.py does not round-trip.

Regarding the round-trip issue in Lib/test/test_typing.py mentioned by SilentGhost: Apparently the following line added in b891c465bb7d38a597c5c2ad547d7b19194f4dad triggers an issue in Tools/parser/unparse.py Literal[b"foo", u"bar"] As this is more likely an issue in unparse.py instead of test_typing.py, I opened another ticket for tracking: #37053.
