Why would a Scala Worksheet using Scala-IDE give this as an error?

Question

In a Scala worksheet I can do this:

object Play {

 println("Playing a bit")                         //> Playing a bit

 case class X(a: Int = 1, x: List[X]){
 }

}

but I can't do this:

object Play {

 case class X(a: Int = 1, x: List[X]){
 }

}

In the latter it will complain after the case class that ; was expected but import found

This seems to be a bug that is fixed in the latest nightly build of Scala IDE. See https://stackoverflow.com/a/12767214/770361
