Crash on definition of TypedDict method #5653
Description
I'm not sure if this is a bug or a feature, but I was considering migrating from NamedTuple to TypedDict, and ran into a problem where methods don't seem to be supported on TypedDicts.
class User(TypedDict):
id: str
firstName: str
lastName: str
password: str
# error:Invalid statement in TypedDict definition; expected "field_name: field_type"
@classmethod
def from_row(cls, row: RowProxy) -> typing.Optional["User"]:
if not row:
return None
return User(id=row.id, firstName=row.first_name, lastName=row.last_name)Despite the error, the code runs fine. So, I'm looking for clarification that this is / isn't a bug, and maybe some reasoning about
