title: Scala - can yield be used multiple times with a for loop?
body: <p>An example:</p>
  
  <pre><code>val l = List(1,2,3)
  val t = List(-1,-2,-3)
  </code></pre>
  
  <p>Can I do something like this?</p>
  
  <pre><code>for (i &lt;- 0 to 10) yield (l(i)) yield (t(i))
  </code></pre>
  
  <p>Basically I want to yield multiple results for every iteration.</p>
