* One possibility would be to check the current token, and use that to
* determine if we would output JSON Array, Object or scalar value.
* Jackson 1.5 did NOT include any type information; but this seems wrong,
* and so 1.6 WILL include type information.
*
* Note that we just claim it is scalar; this should work ok and is simpler
* than doing introspection on both serialization and deserialization.
