code:

function (context, args) {
    var l = #s.scripts.lib(); // useful trust-provided library
    try {
        l.log("trying something risky now"); // l.log() adds the JSON string of whatever its passed to an internal array
        var result = something_risky(); // stand-in for your at-risk code
        l.log(result); // works on objects/arrays too
        return result;
    } catch (e) {
        return [e.stack, l.get_log()]; // l.get_log() returns the stored array, game automatically parses an array (or an array in an array) as a series of newlines
    }
}
