code: public static final <T extends Comparable<? super T>> boolean overlaps(Tuple2<T, T> left, Tuple2<T, T> right) {
          return left.v1.compareTo(right.v2) <= 0
              && left.v2.compareTo(right.v1) >= 0;
      }

  <code><pre>
  // true
  range(1, 3).overlaps(range(2, 4))
  
  // false
  range(1, 3).overlaps(range(5, 8))
