Every time you use an enum, it's replaced with its value. So, if an enum is an 
AA, then that literal is copy-pasted everywhere that the enum is used. So, it 
would almost certainly be foolish to use it anywhere other than to assign to a 
variable (and then all of the operations are done on the variable). Really, 
having an enum that's an AA is almost certainly a foolish thing to do. It's 
one case where the behavior of enums doesn't help and definitely hurts.
