The first problem here is not about sets or unions or anything. The issue is with_items wants a single list to walk over, not a list of two lists.
So with_items: variable_ame works as does with_items: - dog - cat - fish With hard coded strings But if you want to walk two lists, that's "with_nested". Here, though you do want to add them together. I just wanted to mention why you were seeing "groups["A"]" literally in the first logfile above. On Thu, Jun 5, 2014 at 10:26 AM, C.
