Looks like I added this in (#2223), but that was before EagerDataFrame inherited collect from CompliantLazyFrame

Current typing produces this weird edge case where we warn on.lazy().lazy() but don't on .collect().collect()

import pandas as pd

import narwhals as nw

data = {"a": ["A", "B", "A"]}
df = nw.from_native(pd.DataFrame(data))

compliant = df._compliant_frame
compliant.lazy(None)
compliant.lazy(None).lazy(None)  # type: ignore[attr-defined]

compliant.lazy(None).collect(None)
compliant.lazy(None).collect(None).collect(None)  # shouldn't be supported in typing
