Atom "A Little Reflection", object/ trait Name

[waij]

In atom A Little Reflection you introduce an object and a trait Name to add a toString to any class. It is unclear to me why the object is needed. This code without an object seems to work equally well:

trait Naam {
override def toString =
currentMirror.reflect(this).symbol.toString.replace('$', ' ').split(' ').last
}
class Noot extends Naam
println((new Noot).toString) // ---> 'Noot'

Your example on page 268 runs just fine:

class Solid2(val size:Int) extends Naam { //...
s2 is "Solid2(47)"
