到达目的地的途径有多种。不过，沿途不变换道路是永远不会到达终点的。

There are many paths you can follow to reach your destination. However, you'll never reach the end if you keep changing paths along the way.

请记住，同String一样，上面的每种变换都返回一个新rope；原来的rope保持不变。

Keep in mind that, as with String, each of these mutations returns a new rope; the original is left unmodified.
