Section 4- AnyVal and an irrelevant (?) mention of type classes

[ittaiz]

Hi,
At the risk of embarrassing myself with bad Scala-fu I think there is a mistake towards the end of the 4th section.
It says: "In the above example I’ve used a TypeClass Checker[T] and a type bound" but the example just has a method taking an AnyVal. I have a feeling the text is leftovers from a more complex precious example.
Right/Wrong?
