>>> df = pd.DataFrame({'A': [1, 1, 1]})
>>> df.loc[1, ..., ...] 
... # IndexingError: Too many indexers
>>> df[pd.Series([True], dtype=bool)] 
... # IndexingError: Unalignable boolean Series provided as indexer...
>>> s = pd.Series(range(2),
...               index = pd.MultiIndex.from_product([["a", "b"], ["c"]]))
