> Are there any additional tests which we should add to improve coverage for
the parallel writer?
I think if we could including tests that write lists of structs and structs
of lists that would also be good
Perhaps like
```sql
❯ select [struct('foo', 1), struct('bar', 2)];
+-----------------------------------------------------------------------+
| make_array(struct(Utf8("foo"),Int64(1)),struct(Utf8("bar"),Int64(2))) |
+-----------------------------------------------------------------------+
| [{c0: foo, c1: 1}, {c0: bar, c1: 2}] |
+-----------------------------------------------------------------------+
1 row in set. Query took 0.002 seconds.
```
```sql
❯ select struct('foo', [1,2,3], struct('bar', [2,3,4]));
+-----------------------------------------------------------------------------------------------------------------------+
|
struct(Utf8("foo"),make_array(Int64(1),Int64(2),Int64(3)),struct(Utf8("bar"),make_array(Int64(2),Int64(3),Int64(4))))
|
+-----------------------------------------------------------------------------------------------------------------------+
| {c0: foo, c1: [1, 2, 3], c2: {c0: bar, c1: [2, 3, 4]}}
|
+-----------------------------------------------------------------------------------------------------------------------+
1 row in set. Query took 0.003 seconds.
