      ranges = sorted(ranges, key=op.attrgetter('start'))
      return sorted_diff(ranges, group_ranges(ranges))
docs: Return any ranges that intersect.
  
      Parameters
      ----------
      ranges : iterable[ranges]
          A sequence of ranges to check for intersections.
  
      Returns

      intersections : iterable[ranges]
          A sequence of all of the ranges that intersected in ``ranges``.
  
      Examples
      --------
      >>> ranges = [range(0, 1), range(2, 5), range(4, 7)]
      >>> list(intersecting_ranges(ranges))
      [range(2, 5), range(4, 7)]
  
      >>> ranges = [range(0, 1), range(2, 3)]
      >>> list(intersecting_ranges(ranges))
      []
  
      >>> ranges = [range(0, 1), range(1, 2)]
      >>> list(intersecting_ranges(ranges))
      [range(0, 1), range(1, 2)]
