title: Unmatched closing ')' pattern exception
body: <p>I have this regular expression:</p>
  
  <pre><code>"\\(d+)(,)\\(w+)(,)\\(w+)(,)\\(w+)(,)\\(\")(d+)(,)(d+)(.)(d+)(\")(,)\\(w+)(,)\\(w+)(,)\\(w+)";
  </code></pre>
  
  <p>and I'm getting this message: </p>
  
  <blockquote>
    <p>Unmatched closing ')' near index 3</p>

  <p>Can someone please give me a hint as to what's wrong with my regular expression?</p>
