Something like this:
```scala
object CreateNamedStruct {
def nameColumns(expressions: Seq[Expression]): Seq[Expression] = {
expressions.zipWithIndex.flatMap {
case (named: NamedExpression, _) =>
Seq(Literal(named.name), named)
case (expression, index) =>
Seq(Literal(s"col$index"), expression)
}
}
def unnamed(expressions: Seq[Expression]): CreateNamedStruct = {
CreateNamedStruct(nameColumns(expressions))
}
}
// You could even drop the CreateStruct entirely
object CreateStruct {
def apply(expressions: Seq[Expression]): Expression = {
CreateNamedStruct.unnamed(expressions)
}
}
```
