How about also removing the {} as an empty dictionary?  Then both
dictionary and set literals will require at least one item to be valid.  No 
  confusion, and {} is not allowed because it's ambiguous (to users) as to 
weather it's a set or dictionary.



Would set({a, b, c}) be valid?

If so, should the repr for a set be set({a, b, c}) instead of
set([a, b, c])?
