Gee, I just found out I could have used an OrderedDict today.  (We're
using a dict that we're now having to add an auxilliary list to to track
when keys are added.)  (This isn't particularly an argument in favor of
adding OrderedDict to stdlib, but it's another use case.  Each dict key
contains a dict value; the subkeys from later-added keys are supposed to
override earlier subkeys.  The original implementation relied on subkeys
being unique, but that doesn't work for our new business requirements.)
