NotImplementedError: BinOp(left=Name(id='ExampleChangeRequestResponseOutageDict', ctx=Load()), op=BitOr(), right=Constant(value=None))

This is triggered by:

ExampleChangeRequestResponseOutageDict = TypedDict(
    "ExampleChangeRequestResponseOutageDict",
    {"outage-seq-id": int, "outage-start-time": str, "outage-end-time": str},
)

ExampleChangeRequestResponseOutageListDict = TypedDict(
    "ExampleChangeRequestResponseOutageListDict",
    {"outages": ExampleChangeRequestResponseOutageDict | None},
)

Command used:

find src -name '*.py' -type f | xargs -n 1 -I {} pyupgrade --py311-plus {}

ah yes, the binary or syntax came way after this rewrite -- should be an easy patch though
