title: What are some example use cases for symbol literals in Scala?
body: <p>The use of symbol literals is not immediately clear from what I've read up on Scala. Would anyone care to share some real world uses?  </p>
  
  <p>Is there a particular Java idiom being covered by symbol literals?  What languages have similar constructs?  I'm coming from a Python background and not sure there's anything analogous in that language.</p>
  
  <p>What would motivate me to use 'HelloWorld vs "HelloWorld"?</p>
  
  <p>Thanks</p>
