title: How to skip line/block/nested-block comments in Boost.Spirit?
body: <p>When parsing a language using Boost.Spirit, how can I ensure that I skip</p>
  
  <pre><code>// line comments
  
  /* block
     comments */ and
  
  /* /* nested
     block */ comments */
  </code></pre>
  
  <p>when reading in the code? At the moment, I just do a <code>phrase_parse</code> into a predefined <code>qi::grammar</code>. I guess what I need is some sort of skipping lexer, right?</p>
