Just my 2 cents, this is just how it's implemented it in jsoncpp (which 
doesn't even attempt to do half of what the proposed library do):
http://jsoncpp.sourceforge.net/
http://jsoncpp.sourceforge.net/class_json_1_1_value.html

To my knowledge JDOM and TinyXML also provides a similar mecanism.

So you may have put your finger on something,
Baptiste.
