Why does Scala place a dollar sign at the end of class names?

In Scala when you query an object for either its class or its class name, you'll get a rogue dollar sign ("$") at the tail end of the printout:

val fizzbuzz : FizzBuzz = new FizzBuzz()
println(s"The class is ${fizzbuzz.getClass}")
println(s"The class name is ${fizzbuzz.getClass.getName}")

This results with:

The class is com.me.myorg.example.FizzBuzz$
The class name is com.me.myorg.example.FizzBuzz$

Sure, it's simple enough to manually remove the "$" at the end, but I'm wondering:

• Why is it there?; and
• Is there anyway to "configure Scala" to omit it?
