Can JSONItem save/retrieve a dictionary in a dictionary?

I need to save to disk a dictionary that contains, among other more prosaic data types, string arrays and a dictionary. I’ve figured out how to save/retrieve the arrays, but no luck with the dictionary. Is this even possible with JSON?

I know if I post a question I’ll come up with the answer as soon as I go back to programming. Sure enough, the answer is yes, a JSON object can hold a Xojo dictionary.
