It's written in C, and so would need an overhaul regardless.  The 
user basically assigns a bunch of function pointers for the 
callbacks.  Using the parser at this level is really kind of 
difficult because you have to create a state machine for parsing 
anything reasonably complex, so what I usually do is nest calls 
to foreachObjectField and foreachArrayElem.  I'm wondering if we 
can't do something similar here, but with corresponding 
ForwardRanges instead of the opApply style.
