Hi, I created the following issue to expose the dictproxy as a builtin type. http://bugs.python.org/issue14386
I would be interesting to accept any mapping type, not only dict. dictproxy implementation supports any mapping, even list or tuple, but I don't want to support sequences because a missing key would raise an IndexError instead of a KeyError. My problem is to check the type in C. issubclass(collections.ChainMap, collections.abc.Sequence) is False which is the expected result, so I need to implement this check in C. "The "PyMapping_Check(dict) && !PyMapping_Check(dict)" fails on ChainMap: type.__new__(ChainMap) fills tp_as_sequence->sq_item slot is defined because ChainMap has a __getitem__ method. Do you have an idea how to implement such test?
