title: Get string indices from the result of re-seq
body: <p>I'm currently using <code>re-seq</code> to find the matches of comments inside a piece of java source code.</p>
  
  <pre><code>(re-seq #"(?:/\*(?:[^*]|(?:\*+[^*/]))*\*+/)|(?://.*)" code)
  </code></pre>
  
  <p>How can I get the index / indices of the matches in the original string <code>code</code>? i.e. To find the starting (and ending) point of the original string <code>code</code>.</p>
