This is *exactly* what I would want if I were designing a language from
scratch.  It's obvious, readable, etc.  However, it also breaks every
single instance of 'newdict = {}' in Python code, which is a very common
idiom.

Unfortunately, I don't really like the proposed empty-set literal proposed
in the thread: '{,}'.  It saves two characters over 'set()', but is not
intuitive to me.
