And you claim to "set the record strait" by posting code that *purposely* raises a NameError when some function parameter is not within a predefined range? That's ludicrous!

Look, i don't want you to think that i am arguing with you, i just want you to show us an example that proves your argument to be true; but you cannot prove the argument by doing foolish things. Imagine the following scenario:

 * CarMakerA claims their new automobile is safest on the

 * CarMakerB purposely drives the car into a ditch and then
   claims the car is unsafe and CarMakerA is a liar.
That's what your example just did! Please provide a "real world" example that proves your argument. I am open to changing my mind *IF* someone can provide proof.
