I like this idea. But I am -1 on returning None if the array is unstructured. I expect .keys(), if present, to always return an iterable.
In fact, this would break some of my existing code, which checks for the existence of "keys" as a way to do duck typed checks for dictionary like objects (e.g., including pandas.DataFrame): https://github.com/xray/xray/blob/v0.3/xray/core/utils.py#L165
