How to use the ember-runtime/mixins/comparable.detect function in ember-runtime

export default function compare(v, w) {
  if (v === w) {
    return 0;
  }

  var type1 = typeOf(v);
  var type2 = typeOf(w);

  if (Comparable) {
    if (type1 === 'instance' && Comparable.detect(v) && v.constructor.compare) {
      return v.constructor.compare(v, w);
    }

    if (type2 === 'instance' && Comparable.detect(w) && w.constructor.compare) {
      return w.constructor.compare(w, v) * -1;
    }
  }

  var res = spaceship(TYPE_ORDER[type1], TYPE_ORDER[type2]);

  if (res !== 0) {
    return res;
  }

  // types are equal - so we have to check values now
  switch (type1) {

var wLen = w.length;
      var len = Math.min(vLen, wLen);

      for (var i = 0; i < len; i++) {
        var r = compare(v[i], w[i]);
        if (r !== 0) {
          return r;
        }
      }

      // all elements are equal now
      // shorter array should be ordered first
      return spaceship(vLen, wLen);

    case 'instance':
      if (Comparable && Comparable.detect(v)) {
        return v.compare(v, w);
      }
      return 0;

    case 'date':
      return spaceship(v.getTime(), w.getTime());

    default:
      return 0;
  }
}

export default function compare(v, w) {
  if (v === w) {
    return 0;
  }

  var type1 = typeOf(v);
  var type2 = typeOf(w);

  if (Comparable) {
    if (type1 === 'instance' && Comparable.detect(v) && v.constructor.compare) {
      return v.constructor.compare(v, w);
    }

    if (type2 === 'instance' && Comparable.detect(w) && w.constructor.compare) {
      return w.constructor.compare(w, v) * -1;
    }
  }

  var res = spaceship(TYPE_ORDER[type1], TYPE_ORDER[type2]);

  if (res !== 0) {
    return res;
  }

  // types are equal - so we have to check values now
  switch (type1) {
    case 'boolean':
    case 'number':
      return spaceship(v, w);
