    There are no silly questions ;-)
    SQL fully integrates NULL in all its operators. So we should also allow it in our APIs
as our runtime allows it anyway. You need it for e.g. `CASE b WHEN 1 THEN 11 WHEN 2 THEN 4
ELSE NULL END`

> The Table API needs support for the null literal e.g. for passing null values to functions.
