title: Uninterpreted strings in YAML
body: <p>Is there a way to have uninterpreted strings within a YAML file?  My goal is to have regular expressions that contain certain escape sequences like <code>\w</code>.  Currently, Python's YAML complains: <code>found unknown escape character 'w'</code>.</p>
  
  <p>I know I could escape them, but this is going to obfuscate the actual regular expression.  Any way around this?</p>
