If it helps, I've recently used huddle[0] to create arbitrarily-nested dictionaries and output JSON of them. It can be quite slow to do a jsondump for large dictionaries though: it sometimes takes a few minutes to output a multi-megabyte file. And, to add to your point, it wasn't even listed on the JSON page you mentioned until the "Misc" conversation section. [0] http://wiki.tcl.tk/21116 http://wiki.tcl.tk/21116
