While implementing, I noticed:
ArrayQueryConstructor are not valid in Spark:
`spark-shell`
```scala
spark.sql("select array(select 1)")
org.apache.spark.sql.catalyst.parser.ParseException:
extraneous input '1' expecting ')'(line 1, pos 20)
== SQL ==
select array(select 1)

Array literals are not uniform accross dialects,
for example Google's BigQuery uses this syntax:
```sql
SELECT [1, 2, 3]
```
