Two points:

   - What happens when a new element is added to the OrderedDict after the user sorts it?

   - If by 'init' you mean something like `d = OrderedDict(a=1, b=2, c=3)` --
     this does not preserve an insertion order as the keywords end up in a
     regular, unsorted dict that is passed to OrderedDict.__init__
