title: Using a configuration of YAML which is tab indented
body: <p>I was writing a unit test, and I discovered a tool that writes YAML configuration with tab indention, but when I tried to read it using <code>yaml.load(file_object)</code> I get an error saying: </p>
  
  <pre><code>(&lt;unknown&gt;): found character that cannot start any token while scanning for the next token at line 2 column 1
  </code></pre>
  
  <p>or with the tool I see in terminal: </p>
  
  <pre><code>while scanning for the next token
  found character '\t' that cannot start any token
    in "/user/config/settings", line 2, column 1
  </code></pre>
