Another interesting property from pull parsers is that you can implement
backtracking trivially as I've demonstrated in a branch for an HTTP parser:
https://github.com/BoostGSoC14/boost.http/blob/83b83041de3e8b04cc9475497648f19504d5ce43/include/boost/http/socket.ipp#L1816-L1866

Although I don't see much of use for backtracking in a JSON parser. But the
composition of algorithms on the other side is fantastic. I've been using
your JSON parser at work for some years now and the possibility to skip
several tokens and delegate their processing to different functions works
really well.
