For __or__ we need to copy the content of both mapping to the resulting mapping
in any case. We can implement it as {**self, **other}. We should not use the
copy() method because it is not a part of the Mapping interface.
For __eq__, no copying is needed if we just re-implement Mapping.__eq__ (with
special cases for few known types for performance).
