1351,mistake in Data.Set description,guest,,"Data.set description in HTML documentation contains the following text

difference :: Ord a => Set a -> Set a -> Set a 
O(n+m). Difference of two sets. The implementation uses an efficient hedge algorithm comparable with hedge-union.  
 
intersection :: Ord a => Set a -> Set a -> Set a 
O(n+m). The intersection of two sets. Elements of the result come from the first set.  

I think that phrase ""Elements of the result come from the first set"" relates to difference function, not to intersection",bug,closed,normal,,Documentation,6.6.1,fixed,,,Windows,x86,,Unknown,,,,
