Hmm. So the idea is that all JSON atomic values are considered to be
text strings, even when they look like something else (like bools or
numbers)? That would simplify matters I guess, but I'm not sure about
the usability. In particular I'd want to have something that dequotes
the value so that I can get foo not "foo" when converting to SQL text.
(I'm assuming that quotes would be there normally, so as not to lose
the distinction between 3 and "3" in the JSON representation.)
