Is it expected? No, it looks like a bug. I'd be hard pressed to call
this "syntax", but...

scala> object A { case class Bippy(x: String) }
defined module A

scala> println(A.Bippy("").getClass)
class $line1.$read$$iw$$iw$A$Bippy

scala> :javap $line1.$read$$iw$$iw$A$Bippy
Compiled from ""
public class A$Bippy extends java.lang.Object implements
scala.ScalaObject,scala.Product,scala.Serializable{
public scala.collection.Iterator productIterator();
public scala.collection.Iterator productElements();
public java.lang.String x();
public A$Bippy copy(java.lang.String);
public java.lang.String copy$default$1();
public int hashCode();
public java.lang.String toString();
public boolean equals(java.lang.Object);
public java.lang.String productPrefix();
public int productArity();
public java.lang.Object productElement(int);
public boolean canEqual(java.lang.Object);
public A$Bippy(java.lang.String);
}

Well, you should start out with println(A.getClass) to find the real
name of the class (probably something like $line1.$read$$iw$$iw$A) and
then append $Bippy to that. At least I had success with this before
:javap was disabled on Windows ;-) (at least it tells me so)

Please do.

This is a guess: try A$.Bippy.

Thanks Paul and Roland. That's good enough for me but do you want me
to file a ticket so this doesn't get forgotten?
