All good points. Is this misconception really as common as you suggest
(obviously there aren't really going to be 50,000 previous threads of
this nature - but you know what I mean). Because if they are, it is
perhaps a case for adding optimized sorted_dict and sorted_set to the
collections module, similar to the TreeSet and TreeMap classes in
Java.
