title: In scala, how to pass a default value to List.find?
body: <p>I would like to find an element in a list that matches a predicate and to get a <strong>default value</strong> if no elements matches the predicate. I want to do this idiomatically, without defining additional variables (one liner). 
  Is there something similar to <code>getOrElse</code> of <code>HashMap</code>?</p>
