title: Ternary conditional operator in interpolated strings in F#
body: <p>Is it possible to use the ternary conditional operator in an interpolated string?<br />
  Something like:</p>
  <pre class="lang-ml prettyprint-override"><code>printfn $&quot;&quot;&quot;This is a string{($&quot;, and here's the inner string: {innerString}!&quot; if boolFlag  else &quot;!&quot;)}\n&quot;&quot;&quot;
  </code></pre>
