At the risk of being called pompous, I wish to point out that you 
yourself are not innocent of those charges, choosing the least germane 
part of my message as the only part to discuss. I'll assume you're doing 
the same thing I tend to do--only responding to the parts of the message 
you disagree with.

Oh, I am not so incompetent in reading comprehension as to not know what 
you meant by defensive programming. I was just pointing out that it 
wasn't the definition I have heard used before by giving the definition 
that I used.

And I'd call it "basic principles of good programming." :-)
