title: Scala: Elegant conversion of a string into a boolean
body: <p>In Java you can write <code>Boolean.valueOf(myString)</code>. However in Scala, <code>java.lang.Boolean</code> is hidden by <code>scala.Boolean</code> which lacks this function. It's easy enough to switch to using the original Java version of a boolean, but that just doesn't seem right.</p>
  
  <p>So what is the one-line, canonical solution in Scala for extracting <code>true</code> from a string?</p>
