title: YAML subsequent as substring
body: <p>How to use variables in YAML? Let's get the code</p>
  
  <pre>
  hr:
    - Mark McGwire
    - &SS Sammy Sosa
  rbi:
    - *SS
    - Lorem *SS ipsum
    - Ken Griffey
  </pre>
  
  <p>The <pre>  - *SS</pre> line returns <code>Sammy Sosa</code> string that is OK.</p>
  
  <p>But the <pre>  - Lorem *SS ipsum</pre> line returns <code>Lorem *SS ipsum</code> string as it takes the subsequent <code>*SS</code> literally and does not interpret it.</p>
