Talk:Symmetric difference

The symmetric difference should give one list which is the union of the two differences of the lists. The Perl example shows two lists. --Mwn3d 23:19, 2 December 2009 (UTC)

• I agree with your statement about what “symmetric difference” means.
• All of the current examples produce two sets.
• The task as written tends to the two-lists interpretation.

Conclusion: Either the task should be renamed, or the task description should be clarified and the examples revised. --Kevin Reid 02:02, 3 December 2009 (UTC)

I think the task name is good. Symmetric difference is actually an exercise I did in CS classes a few times. I think the task description should be changed to match the task name. --Mwn3d 02:17, 3 December 2009 (UTC)
