You clearly don't get my point.  I *DON'T* want to use stupid constants 
and stupid equalities, I want to use identities.  I *DON'T* want to use 
stupid ==, I want to use 'is'.  I *DON'T* care how many people with 
years of experience of Python tell me that this is the wrong thing to 
do, that is how I am going to do it.  So, for the final time of asking, 
how do I do the above with, and only with, the identity, even if you 
stupidly keep on trying to tell me that this is wrong?
