I don't understand the need to track emptiness per level. Only the top level array/object can ever be empty, can it?My expectation was that any sub-object or sub-array could be empty. That is, this should be valid (and the JSON parser in Python allows): {"a":{}, "b":[], "c":[[]], "d":[{}]}Sure, but the emptiness of finished arrays and objects doesn't matter for the purposes of error checking, comma setting or closing. At most one of them is empty *and* unclosed while writing the overall JSON object -- the last one opened: { {"a":{ {"a":{}, "b":[ {"a":{}, "b":[], "c":[ {"a":{}, "b":[], "c":[[ {"a":{}, "b":[], "c":[[]], "d":[ {"a":{}, "b":[], "c":[[]], "d":[{ Any of the earlier written arrays/objects are either closed or contain at least a half-done sub-array/object, which makes them non-empty.

good point. i'll revisit. thanks. Jeff
