Hi, Unfortunately paranamer does not work with scala REPL. You need to put LastTimestamp to .scala file, compile it and then add it to the CLASSPATH. Hopefully Scala will get good reflection API some day. The we can remove dependency to paranamer (which is needed to query names of case class constructor parameters).
