Here's the code I use now to extract breakpoint id from response:

            int id = -1;

            if (r.hasField("bkpt"))
                id = r["bkpt"]["number"].literal().toInt();
            else if (r.hasField("wpt"))
                id = r["wpt"]["number"].literal().toInt();
            else if (r.hasField("hw-rwpt"))
                id = r["hw-rwpt"]["number"].literal().toInt();

And there's also "hw-awpt", and in future there might be "catchpoint" and
"fork" and what not. 

If I only want to extract the *id* of breakpoint, why do I need to write
such boilerplate? Or should I write a function that will iterate over all
fields of 'r', and check if that field has nested field called 'number'?
