title: Word array with whitespace
body: <p>I came to love <strong>word arrays</strong>, but today I face a challenge:</p>
  
  <pre><code> &gt; a = %w[ faq contact 'about us' legal 'bug reports' ]
   =&gt; ["faq", "contact", "'about", "us'", "legal", "'bug", "reports'"] 
   &gt; a = %w[ faq contact "about us" legal 'bug reports' ]
   =&gt; ["faq", "contact", "\"about", "us\"", "legal", "'bug", "reports'"] 
  </code></pre>
  
  <p>How can I have <strong>whitespace</strong> an element?</p>
