title: Using Reserved words as fields name
body: <p>I am using external WSDL class for creating apex classes for my project, some of the classes have fields which name is reserved in apex, as <code>limit</code> word.
  My problem here is, i can't call that field, sample example: </p>
  
  <pre><code>System.debug(object.limit);
  </code></pre>
  
  <p>where limit is field in object.
  I can't even save the file because there is error in console saying:</p>
  
  <pre><code>Variable does not exist: limit
  </code></pre>
  
  <p>Any idea how reserved word in this cases can be escaped?</p>
