> The following examples should all return results with zero columns. Check that this behavior is consistent across Tables, RecordBatches, and Datasets. There are some cases currently where these examples return all columns or throw errors.
>  * {{transmute()}}
>  * {{transmute(NULL)}}
>  * {{transmute(x = NULL, y = NULL, z = NULL)}}
>  * {{x = NULL}}
>  {{transmute(x = !!x)}}
