Mypy doesn't assign TypedDict output as Literals

Bug Report

(A clear and concise description of what the bug is.)

To Reproduce

When I do this, I get an error saying a literal is required. When I add a literal it can't assign a string to a literal.

Actual Behavior

When using the first way, I got this error:

main.py:19: error: TypedDict key must be a string literal; expected one of ("b", "c", "d")  [literal-required]
Found 1 error in 1 file (checked 1 source file)

The second way this one:

main.py:19: error: Incompatible types in assignment (expression has type "str", variable has type "Literal['b', 'c', 'd']")  [assignment]
Found 1 error in 1 file (checked 1 source file)

Your Environment

I used the standard strict configuration from vscode, I don't know where I could find the version info and default command-line flags.

Beginne mit den beiden verlinkten mypy-play-Reproduktionen und vergleiche ihr Verhalten bei TypedDict und Literal unter dem gemeldeten Python-3.11/latest-Setup. Als erledigt gilt die Aufgabe, wenn beide Beispiele wie vorgesehen typgeprüft werden, ohne die gemeldeten Fehler „literal-required“ oder „incompatible-assignment“.
