Review comment:
@ulysses-you - does `spark.range(1).select(typedLit(Array()))` get you
the result you're looking for? Per the docs, "The difference between the
typedLit function and lit is that this function can handle parameterized scala
types e.g.: List, Seq and Map." `lit` isn't normally used for collections.
