title: ANTLR grammar for Scala?
body: <p>I am trying to build a static analysis tool for a demo project. We are free to choose the language to analyze. I started off by writing a Java code analyzer using ANTLR. I now want to do the same for Scala code. However, I could not find the ANTLR grammar for Scala. Does it exist? 
  Is there any other machine readable form of Scala grammar?</p>
