The from_yaml function is intended to be able to parse a yaml config for astropy quantities, however this fails as when the yaml object is created here, it is created as a ruamel.yaml.comments.CommentedSeq object. When this object is parsed by the deserialize_all_objects function, it checks if the object is a dict or OrderedDict instance before attempting to parse any entries intended as astropy quantities. As the object is not an instance of either type, it will never be parsed.
