Summary: Choices enum - Inconsistent valuesChoices enum - Inconsistent values.

Choices are supported if you need a concrete data type other than int or str. In such cases you should subclass Choices and the required concrete data type (see documentation and examples), so described usage is not supported. In your case you can use IntegerChoices.

Could we raise an exception in such case then?
Add something like this to metaclass for example:

if classdict._member_names and cls._member_type_ is object:
    raise TypeError(...)
