I do not really agree with the two cons the authors listed. Null handling isn't intuitive in the beginning, but it makes it harder to let missing data go unnoticed. The expression / table thing can be solved like we solved it in OctoSQL[0], and I think others have solved it in a similar way. Whenever you have more than a single scalar value in expression position, just create a tuple, or tuple of tuples out of it, which does act like a single value.
