Ok, I think I begin to see where I'm going wrong.  I'm extending 
'parsing' in my head into what only happens at execution. Another 
difference between a compiled language vs. an interpreted one.  I guess 
parsing, in an interpreted language, is strictly speaking a much simple 
matter.  At run time more work is done.  Thanks.
