I like having "ROWS" in there somehow, because it denotes the distinction from
SQL-standard TABLE(). Suppose we were to implement the SQL-standard TABLE(),
essentially just mapping it to UNNEST(). Then we'd have "TABLE (f())" that
unpacks the single array returned by f(), and we'd have "TABLE FROM (f())"
that unpacks the set of rows returned by f(). The word "FROM" alone does not
indicate that difference the way including "ROWS" does. (I don't object to
having "FROM" in addition to "ROWS".)
