Subject: Operator Overloading <<

Is there a way to overload '<<' in the Array class?

Or perhaps there's a better approach to my problem.  I have a class that
inherits from Array.  I want the user to be able to use my class just
like a standard array.  However, I want to be able to force some code to
run every time a user of my class appends a new item.  I was able to
overload the '+' operator to do this but it doesn't fit with standard
array usage.

Thanks in advance!
