title: Scala TypeTags and performance
body: <p>There are some answers around for equivalent questions about Java, but is scala reflection (2.11, TypeTags) really slow? there's a long narrative write-up about it at <a href="http://docs.scala-lang.org/overviews/reflection/overview.html" rel="nofollow">http://docs.scala-lang.org/overviews/reflection/overview.html</a>, where the answer to this question is hard to extract.</p>
  
  <p>I see a lot of advice floating around about avoiding reflection, maybe some of it predating the improvements of 2.11, but if this works well it looks like it can solve the debilitating aspect of the JVM's type erasure, for scala code.</p>
  
  <p>Thanks!</p>
