title: using @include inside inline element in jade/pug template
body: <p>is their a way to include an external document at compile time inline and inside a tag with text using jade/pug templating?</p>
  
  <p>for example, something like:</p>
  
  <pre><code>p paragraph text content with #[span.icon @include path_to_file/icon.svg] inline svg thrown into the html document
  </code></pre>
  
  <p>but not this solution:</p>
  
  <pre><code>p paragraph text content with #[span.icon #[svg #[use(href='path_to_file/icon.svg')]]]
  </code></pre>
  
  <p>i know the later works, but i'm looking for a solution that doesn't use the use tag or an external reference</p>
  
  <p>solution needs to result in importing the document inside the tag in between the words at compile time.</p>
  
  <p>i've looked through the pug documentation many times. only things close to this are tag interpolation and block expansion, but they don't seem to allow for this situation specifically.</p>
  
  <p>thanks!</p>
