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.
