Review Comment:
qq: Maybe seems like the Scala side even doesn't allow for the single
`Column` case ??
```scala
scala> df.select(lit(df.id)).show()
<console>:24: error: value id in class Dataset cannot be accessed in
org.apache.spark.sql.Dataset[Long]
df.select(lit(df.id)).show()
```
which is allowed in Python side:
```python
>>> df.select(F.lit(df.id)).show()
+---+
| id|
+---+
| 0|
| 1|
| 2|
| 3|
| 4|
| 5|
| 6|
| 7|
| 8|
| 9|
+---+
```
