title: Does Scala have an API method that converts a Seq[Option[T]] to Seq[T]?
body: <p>Is there a Scala API method to convert a <code>Seq[Option[T]] -&gt; Seq[T]</code>?</p>
  
  <p>You can do this manually via:</p>
  
  <pre><code>seq.filter(_.isDefined).map(_.get)
  </code></pre>
  
  <p>Wondering if there is a method that does the above in the general API.</p>
