I understand all these concepts in a Python context quite well, but understanding a PyWart is no validation for it's continued existence. You probably understand the common cold quite well. If you do you'll wash your hands before eating, and avoid exposure to sick people. THAT'S CALLED A WORKAROUND! But disease is not yet fully under human control, we are forced to used the workaround. Whereas, languages are. So designing a language poorly and then getting upset because people don't praise your clunky work-around is ludicrous. Psst: THE PROBLEM IS SELF-INDUCED! Mankind, the only creature dumb enough to self-induce his own hardships -- somewhere a higher intelligence must be laughing... or crying, who knows. *sigh*
