Would it be practical to add deprecated methods to regular dict for the OrderedDict
reordering methods that raise with an error suggesting "To use this method, convert
dict to OrderedDict." (or some better wording).
That's an interesting idea. Regular dicts aren't well suited to the reordering
operations (like lists, repeated inserts at the front of the sequence wouldn't
be performant relative to OrderedDict which uses double-linked lists
internally). My instinct is to leave regular dicts alone so that they can
focus on their primary task (being good a fast lookups).
My goal was just to give a meaningful error message if someone misses
the implications in What's New, and has code that actually does expect
named_tuple.as_dict to have the ordering operations.
The added, deprecated methods could be removed after a couple of versions.
