> DuckDb has popularized allowing trailing commas in the SELECT list.
> The benefit of this ability is that it is easy to add, remove, comment out
> expressions from the select list:
> {noformat}
> SELECT c1,
> /* c2 */
> FROM T;
> vs
> SELECT c1
> /* , c2 */
> FROM T;
> {noformat}
> Recently Snowflake jumped onto this usability feature as well.
