title: Show default content in a template if an object is nil otherwise show based on the set property
body: <p>In my template, I would like to include some default <code>meta</code> tags (90% of the time). However, when a specific property is set, I would like to show a different set of text.</p>
  
  <p>I know I can set an anonymous <code>struct</code> and set a property with either <code>"default"</code> or <code>"some-x"</code>. However, this means, I need to add an anonymous struct to 90% of my handlers that just currently pass <code>nil</code>. </p>
  
  <p>Is there way to do something like</p>
  
  <pre><code>{{if eq . nil}} 
     // default meta tag
  {{else if eq .MetaValue "some-x"}} 
     //other
  {{end}}
  </code></pre>
  
  <p>If I try something like my above code, it compiles but doesn't do what I want. Appreciate any suggestions on how to handle  it properly without adding a lot of boiler plate. </p>
  
  <p>Thanks!</p>
