We should be using the (relatively new) nsFrameList::Enumerator class for frame-list-iteration where possible, instead of directly walking a frame list.
nsColumnSetFrame::BuildDisplayList currently walks directly over its child list. Filing this bug on switching it to using nsFrameList::Enumerator.

FWIW, I just cribbed the Enumerator "for" loop line from here:
I'm curious whether you guys think the intent was that we use nsFrameList::Enumerator this way. (I originally suggested it to dholbert, but then he pointed out that code like this wasn't converted when nsFrameList::Enumerator was introduced.)
Yes, I think the intent was to convert frame list loops in this way.
I certainly do it whenever I get the chance. Please r- me if you
see I don't :-)
