I find it hard to make a column names version of API:
```scala
def namedStruct(fieldName: String, col: String, fieldAndCols: String*):
Column = ???
```
It would limit creation of Literal field using the API above, and when we
change the API to the below one:
```scala
def namedStruct(fieldName: String, col: Any, fieldAndCols: Any*): Column
= ???
```
When we have String in even positions, it's impossible to tell if the user
want to create a String Literal or refer to a col
