I can't see much advantage over:
for key in sorted(mydict):
...
A much simpler data-structure, that is also very useful, is a
dictionary that keeps insertion order -- it's also something that's a
tad bit more difficult to implement yourself than the above. My
personal implementation is documented at
http://blog.tkbe.org/archive/python-property-set/
It's very tempting to add value access by numerical index (I did as
well), however I now think it's a mistake.
-1 from me.
