This class is to test that the flags implementation does not assume the semantics of attributes. This is to avoid code such as: ```python if hasattr(obj, lock): obj.lock() ``` which will fail if `obj` has an attribute `lock` that does not behave in the way we expect. This class only has unusable attributes. There are two exceptions for which this class behaves normally: * Python's special functions which start and end with a double underscore. * `valid_attribute`, an attribute used to test the class. For other attributes, both `hasttr(obj, attr)` and `callable(obj, attr)` will return True. Calling `obj.attr` will return a function which takes no arguments and raises an AttributeError when called. For example, the `lock` example above will raise an AttributeError. The only valid action on attributes is assignment, e.g. ```python obj = UnusableConfig() obj.attr = 1 ``` In which case the attribute will keep its assigned value and become usable. cCs d|_dS)Né©Ú_valid_attribute©Úself©r úg/home/ubuntu/.local/lib/python3.10/site-packages/ml_collections/config_flags/tests/configdict_config.pyÚ__init__5s zUnusableConfig.__init__cs2ˆ d¡rˆ d¡rtd ˆ¡ƒ‚‡fdd„}|S)aëGet an arbitrary attribute.
