Fri 11 Jun 2004 11:06:05 AM UTC, comment #1:  This was very well explained by William Sit in http://lists.gnu.org/archive/html/axiom-developer/2004-06/msg00087.html Therefore, this bug is really identical to bug #9297	Martin Rubey <kratt6>
Fri 04 Jun 2004 08:00:01 AM UTC, original submission:   box promises that its argument is not evaluated. However this does not work always, it seems: (1) -> box(sum(i,i=1..n))          2         n  + n    (1)  ------            2                                                      Type: Expression Integer even worse: (2) -> sum(box(i),i=a..b)         (b + 1)b - aa - 1    (2)  -----------------                 2 Maybe I missunderstood the documentation...
