A design criteria for this library is to require only C++11

If you mean something like

    json::value jv = co_await parse(source);

I think that the inversion of the flow of control resulting from this
design has excessive impact on the rest of the code. If we wanted to
retrieve a JSON document from a socket for example, then `source`
would have to be a coroutine. In the current design, the parser does
not impose any model as to how the data buffers are acquired. I could
be wrong though, do you have a more complete example?

Thanks
