Mark, it's clear you're passionate about computer science, but with all 
due respect, you need to learn more about it.  "Real OOP" is a misnomer: 
every language brings its own style of OOP, none more legitimate than 
any other.  And your earlier idea that punched cards didn't have tokens 
is wildly ignorant of the state of software and languages 50 years ago.
