So it appears that JSON can be in one of 3 useful states:

1. a range of characters (rc)
2. a range of nodes (rn)
3. a container of JSON values (values)

What's necessary is simply the ability to convert between these states:

(names are just for illustration)

    rn = rc.toNodes();
    values = rn.toValues();
    rn = values.toNodes();
    rc = rn.toChars();

So, if I wanted to simply pretty print a JSON string s:

    s.toNodes.toChars();

I.e. it's all composable.
