Hi Michael,

I am currently endeavouring to write a DOM-free JSON reader/writer. This 
is the writer: https://github.com/giacomodrago/minijson_writer, the 
reader is in the workings.

I do believe JSON reading and writing is I/O business and should be 
implemented as such. The JSON writer I released is not the usual 
object["field"] = value thing, it is a decorator around a stream. It 
does not allocate memory. One rarely performs DOM manipulations on a 
JSON object. I don't quite see the point of building an in-memory 
object, and allocate multiple buffers on the heap just for the sake of 
serialising the object immediately after, and then throwing everything away.

As for the reader, I am designing it in a way that memory allocations 
can be kept to the very minimum, for example it will be possible to 
optionally re-use the provided input buffer for storing the parsed tokens.

I'd be happy to receive your feedback, and if you think this may be a 
nice addition to Boost, you may back my application for a review process.

Best
Giacomo
