It's already implemented, here's an example of code:

var jObj = JSON.stringify(r.args);

Incoming headers of a request are represented in r.headersIn read-only
object, so it's possible to implement some additional logic, like the
following one:

for (var h in r.headersIn) {
    // where:
    // h is the header's name of a request
    // r.headersIn[h] is the header's value
}

Hope that helps.
