Raymond Hettinger added the comment: Until regular dicts guarantee order, I don't want to go down this path for ChainMap which currently makes no guarantees about preserving and passing through properties of the underlying mappings. The current implementation is short, fast, and reliable. I don't want to trade any of those for a feature that we don't even guarantee for regular dicts.
