          Description

          mysql> select weekday(now()),dayname(now()),dayname(now())+1;
+----------------+----------------+------------------+
| weekday(now()) | dayname(now()) | dayname(now())+1 |
+----------------+----------------+------------------+
|              2 | Wednesday      |                3 |
+----------------+----------------+------------------+
1 row in set (0.00 sec)

          3 is wrong for the third column.
          It's not clear why 'Wednesday'+1 should return 3.
          The expected result is 1 with a warning.

                should we document it or fix?

                I'd better fix this.
                We have WEEKDAY() for use as a number.
