title: Is there a non-immutable way to change tuple to list in scala?
body: <p>In scala I want to access specific index of tuple without using <code>tuple._index</code> form</p>
  <p>So I came up with an idea that after changing tuple to list, and then accessing index of list. However, since my project doesn't allow immutable function, I have no idea how to change it. How can I implement the code? Or is there a better way to access specific index of tuple?</p>
