   Sorry for late response - I have been busy for non-working stuff for the last week (I flew to Korea and had to arrange some other stuff).
   
   re https://github.com/apache/spark/pull/23882#issuecomment-467047983 and https://github.com/apache/spark/pull/23882#issuecomment-467063994.
   
   This pattern is the same for Padnas usecase as well. PySpark tried to make the usecase like Pandas as well. It is useful in practice.
   
   ```python
   >>> a = pandas.DataFrame([{'a': 1}])
   >>> a.a
   0    1
   Name: a, dtype: int64
   >>>
   ```
   
   It's short and easier to explicitly refers a column against a target dataframe. I agree with `df["col"]` is more reliable way.
