title: How to convert List to ListBuffer?
body: <p>Is there any way to efficiently do this, perhaps through toBuffer or to methods? My real problem is I'm building a List off a parser, as follows:</p>
  
  <pre><code>lazy val nodes: Parser[List[Node]] = phrase(( nodeA | nodeB | nodeC).*)
  </code></pre>
  
  <p>But after building it, I want it to be a buffer instead - I'm just not sure how to build a buffer straight from the parser.</p>
