code: function computeStackTraceOfCaller(depth) {
          depth = (depth == null ? 0 : +depth) + 1; // "+ 1" because "ofCaller" should drop one frame
          try {
              throw new Error();
          } catch (ex) {
              return computeStackTrace(ex, depth + 1);
          }
      }
