no error on invalid argument to `dataclass_transform`

[DetachHead]

Describe the Bug

from typing import dataclass_transform


@dataclass_transform(asdfsadf=True) # no error
def dataclass[T: type](t: T) -> T:
    return t

from the spec:

• kwargs allows arbitrary additional keyword args to be passed to dataclass_transform. This gives type checkers the freedom to support experimental parameters without needing to wait for changes in typing.py. Type checkers should report errors for any unrecognized parameters.

pyright reports an error in this case
