Comment (by SimonKing):
I wonder: Would it make sense to implement a generic comparison for maps,
based on the dictionary returned by `self._extra_slots({})`? Namely, these
data are used for pickling and copying of maps, and thus it seems
reasonable to me that two maps are equal if and only if the pickling data
coincide.
What do you think? Worth trying? Better be done on a different ticket?
