title: Passing variables inside rails internationalization yml file
body: <p>I want to use variables declared in yml file right there.
  For example, I declared <code>site_name</code> and want to use it below in <code>description</code>.</p>
  
  <pre><code>en:
    site_name: &amp;site_name "Site Name"
    static_pages:
      company:
        description: *site_name #this works fine
        description: "#{*site_name} is an online system" #this doesn't work
  </code></pre>
  
  <p>How can I combine <code>*site_name</code> variable with additional text?</p>
