Unfortunately, `Dataset` (or `Dataframe`) seems not suitable to achieve the
goal on Python.
```python
>>> spark.parallelize(range(1, 10)).toDS()
...
AttributeError: 'RDD' object has no attribute 'toDS'
>>> spark.parallelize(range(1, 10)).toDF()
...
TypeError: Can not infer schema for type: <type 'int'>
```
I'll think about this more until tomorrow and close this if I cannot find a
neat solution.
