   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).

   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.
