Hi Debra:

thank you very much for your message. It is very good to know what
your expectations are for the course; I hope I will live up to them.

I am very pleased about your positive evaluation of the first
lecture; and even more so since you are someone with a lot of experience
in software development in industry.

We both agree that there is something behind the idea of making
the Visitor Pattern executable. We will talk a lot more about this ...
and I hope to give you many more arguments to convince your peers.

By the way, this class is shaping up to be the most influential 
in changing the way I solve problems.   I've read parts of the 
Design Patterns text, but this class is helping to tie the concepts 
to implementation.  I've tried to sell one of my peers on the 
visitor pattern in the past and been unsuccessful because he 
thought it made the code more difficult to support 
(due to the loose coupling).  
But he's wrong!  I've been using a few of these concepts during 
my entire career (15+ years) - even when writing in COBOL 
(although the language makes it more difficult).  
I hope to get two things from your class.  First, 
more ideas and better use of the ones I have.  
Second, a way to verbalize them so I can sell them to my peers.

Thanks a bunch!
Deb Bacon
