I think that this was a bug in WebKit shipping with Safari 2, fixed in Safari
3. However, it's still a bad idea to use for-in with NodeLists. For-in
enumerates all properties of NodeList, so you get not only loop 0...loop 4, but
also loop length and loop item. This is rarely what is needed.

I'm getting identical results in Firefox.

Since this bug doesn't contain any issues identified as bugs, I'm closing it as
INVALID. Please feel free to open new bugs if you disagree - this one contains
a lot of confusion between arrays and NodeLists, so it would be better to avoid
continuing the discussion here.
