> It is because of this, I think we now only coerce to list if the flag is
set
Are you saying that the function should look something like this?
```Rust
fn array(
array_type: &DataType,
array_coercion: Option<&ListCoercion>,
) -> Option<DataType> {
match (array_type, array_coercion) {
(
DataType::FixedSizeList(field, _),
Some(ListCoercion::FixedSizedListToList),
) => Some(DataType::List(Arc::clone(field))),
(
DataType::List(_)
| DataType::LargeList(_)
| DataType::FixedSizeList(_, _),
_,
) => Some(array_type.clone()),
_ => None,
}
}
```
Doing that causes some tests in `array.slt` to fail and I'm not really sure
why. It also doesn't match the previous behavior.
