It's not very good from prql devs to use artificially bloated (line wise) examples to show SQL is bad.

   from employees
   select {id, first_name, age}
   sort age
   take 10

vs

    SELECT
      id,
      first_name,
      age
    FROM
      employees
    ORDER BY
      age
    LIMIT
      10

Huh? For simple queries SQL is simple. You can't beat it on this field.
