:Yeah but to deal with the duplicates issue all you have to do is run the [[Create a Sequence of unique elements]] task on the inputs to get rid of duplicates. --[[User:Spoon!|Spoon!]] 05:42, 2 February 2010 (UTC)
::Oh, I don't think it is hard to do, I just think that because we are dealing with sets then it isn't right to have the chance of duplicates in outputs. --[[User:Paddy3118|Paddy3118]] 07:23, 2 February 2010 (UTC)
:::Alright, this doesn't make sense to me. I understand what you said in the [http://rosettacode.org/mw/index.php?title=Symmetric_difference&diff=74493&oldid=prev log entry], and I'll admit I was unfamiliar with that requirement of "set", but if we're insisting on a strict definition of "set", I don't see how it makes sense to hold examples in languages without a set type to a different requirement. If the data passed into the program has duplicates within a list, then that list isn't a set. I would recommend leaving the note, but reducing it to a "optionally, verify your inputs," rather than a language-attribute-conditional requirement. --[[User:Short Circuit|Michael Mol]] 15:12, 9 February 2010 (UTC)
