[New-bugs-announce] [issue47166] Dataclass transform should ignore TypeAlias variables

[Thomas MK]

New submission from Thomas MK <tmke at posteo.net>:

The dataclass transformation ignores attributes that are annotated as ClassVar. I think it should also ignore attributes that are annotated as TypeAlias.

Specifically, I have this usecase in mind:


class RunMode(Enum):
    release = auto()
    debug = auto()

@dataclass
class Run:
    Mode: TypeAlias = RunMode
    mode: Mode = Mode.release
