 Scala is a Java-compatible programming language with many
 modern language features. It is Java-compatible in that
 Scala and Java classes can directly reference each other and
 subclass each other with no glue code needed. It
 includes modern language features such as closures,
 pattern-matching, parametric types, and virtual type members.
