Well, you get a possible reference loop when you add the set to itself. If you have an array a of references, and add a reference to the array a to itself, then any algorithm that doesn't limit the nesting depth could get in trouble - the data structure's graph would have loops, and that could translate to infinite program loops, much as Russell set up a logical loop. OTOH, we're quite used to dealing with graphs with cycles by now. ;)

I admire this. I've never managed to keep this up through a whole book; the times when I sit back and ponder are usually selected intuitively.
