I've found using the set type to be the quickest way to do many of
these tasks. That leads me to another problem: how to cast / convert
sets as something else afterwards


What's the best (i.e. Pythonic) way to do this?
I need to generate a set (lots of intersections involved), but then I
need to display it sorted

        lstBugsChanged = [ bugId for bugId in setBugsChanged ]
        lstBugsChanged.sort()
