Actually, if they read front-to-back, they'll see collections, and then
read about Collections.  However, I take your point (Collections were
added after most of that earlier stuff was written, and you run out of
synonyms after a while).  How does "group" strike you for the generic
term (can't use "set";  can't use "Bag")?

I'll fix the terminology.  As it happens, I'm working on the Collections
material right now.  What additional material about Collections would
you suggest?
