Good point.  The code above would only work if you didn't care about the 
order of elements.  I'm half inclined to pull the example, but the 
original was due to Michele Simionato, and I haven't quite convinced 
myself yet that you couldn't hack it to have ETObject append to an 
internal list somehow to keep order.  Michele?  Did you have a plan for 
how this would work?
