Dennis Sweeney <sweeney.dennis...@gmail.com> added the comment:
PR 20749 gives each dict view access to a mappingproxy for the original dict,
although I don't know if that defeats the original purpose.
It might be hard to sensibly make MappingProxy(d).items() return something
other than d.items(), since this is already the behavior for user-defined
classes:
>>> class A:
def __getitem__(self, key):
return "value"
def items(self):
return 17
>>> from types import MappingProxyType
>>> MappingProxyType(A()).items()
17
