I think you are getting confused between private data and public data.

The code that Nick set was for private data in classes that inherit from
a base class. This is to ensure that sub-classes do not destroy
data used by the parent class.

Passing data in the contructor is public data, it is set by the user
and not by a sub-class.

In otherwords there should be two methods. One for the user, say data(),
and one for sub-classes that want to ensure data integrity, say private_data()
