title: How can I access the AST that LESS generates?
body: <p>I'd like to perform some code analysis on a LESS stylesheet by accessing the <a href="https://en.wikipedia.org/wiki/Abstract_syntax_tree" rel="nofollow">AST</a>. The <a href="http://lesscss.org/usage/#programmatic-usage" rel="nofollow">programmatic usage</a> documentation only covers how to render a file or string.</p>
  
  <p>How can I access the <a href="https://github.com/less/less.js/" rel="nofollow">less.js</a> AST?</p>
