Note 48: This could bring up the question: “Can a Class Helper be attached to more than one class?” I think the answer is no, although if you attach it to a base class, inherited classes will have the methods available as well.
This is a comment to a sample class helper that adds enumeration support to the TObjectList class, that by default inherits the generic pointer-based TList enumerator.
