The type has a custom __eq__: https://github.com/python/cpython/blob/v3.11.1/Objects/descrobject.c#L1906 This helps fix this mypy false positive when using `--strict-equality`: ``` from types import MappingProxyType p = MappingProxyType({'x': 1}) d = {'x': 1} print(p == d) # error: Non-overlapping equality check ``` The fragment prints `True` so the comparison is valid.
