I agree. I thought enum were invented as a shorthand way of doing ...

   const int red = 1,
             blue = 2,
             green = 3;

Instead we can do 'enum colors { red, blue, green }'

To saving the coder having to recalculate the 'enumerated' names when some  
were added or deleted.

   const int red = 1,
             yellow = 2,
             blue = 3,
             green = 4;

Instead we can do 'enum colors { red, yellow, blue, green }'

Otherwise they are just constants of varying values.
