title: Are parameters of type List or Set in Slick Query Templates possible? (Lifted API)
body: <p>Is it possible to use collections as Parameters in precompiled Slick queries?</p>
  
  <p>Something like:</p>
  
  <pre><code>private val findByIds = for {
    ids &lt;- Parameters[Set[Int]]
    meta &lt;- AssetMetadatas if meta.id inSet ids
  } yield meta
  </code></pre>
  
  <p>Unfortunately the above does not compile:</p>
  
  <p>Don't know how to unpack scala.collection.immutable.Set[Int] to scala.collection.immutable.Set[Int] and pack to Any
        ids &lt;- Parameters[Set[Int]]
                         ^</p>
