As specified in the latest draft:
1. JSON.stringify(symbol) returns undefined.
2. JSON.stringify([symbol]) returns "[null]".
3. JSON.stringify(object) skips any symbol-keyed properties on the object.
So far, so good, I guess. A little wonky maybe, but JSON doesn't have
symbols, so sure.
This struck me as funny though:
4. JSON.stringify(object) also skips symbol-valued properties.
That is, JSON.stringify({"x": Symbol()}) == "{}". I don't know that
there's anything more useful it should be doing instead. Thoughts?
