Lists/Maps/Sets (Was Re: The story of E, part 2 (fwd))

[Mark S. Miller]

Ok, if no one has any good objections, I'm happy with 


"snapshot" vs "revise", and

             |        Table     	     List
  -----------+------------------------------
   immutable |   FinalTable     	FinalList
             |
    mutable  |   DraftTable       	DraftList


"If you've got a table/list/foo that's like something you want, to revise
you edit a draft, until a snapshot of your draft is a good final version."
