WITH enables the possibility to fire subqueries as often as wanted without the need of actual records being selected.
E.g.:

10.sql = SELECT 10 AS _myCount
20 {
  sql = WITH RECURSIVE CountNumbers AS (
        SELECT 1 AS Number
        UNION ALL
        SELECT Number + 1
        FROM CountNumbers
        WHERE Number < '{{myCount:R0}}'
        )

        SELECT Number FROM CountNumbers

  30 {
    sql = SELECT '<br>'
  }
}
