This doesn't strike me as needing an optimization through a dedicated method.
maybe a new dict mapping type -- "shared_dict" -- it would be used in places like the csv reader where it makes sense, but wouldn't impact the regular dict at all.
you could get really clever an have it auto-convert to a regular dict when any changes were made that are incompatible with the shared keys...
