Ordered dict is a dict that preserves insertion order (and exposes via
iteration-related methods like __iter__ and the views).  That's it.
It is not a dict that also implements Sequence.  Keep in mind that
OrderedDict is a fairly simply adaptation of dict.  Unfortunately
there is a lingering temptation to think of it as a sequence.
