    I have a feature request within the JSON plugin. (Not sure if this is the right venue
for this...) Right now, if you specify an element within the JSON that corresponds to further
nested objects or arrays, you just get null. I'd like to be able to coerce the nested object
as a JSON string. This would be especially useful for structures that have variably-sized
nested contents. For example, the Twitter API's `entities` object has an array under the `hashtags`
key. It would be nice if specifying `"entities.hashtags" text` within the external table would
give you a text representation of the array (e.g. `["tag1", "tag2", "etc"]`). 
    
    If this isn't the right place, let me know where to post such a suggestion. Thanks.
