Those are for anonymous enums. Enum is also the keyword for manifest  
constants (think #define)

The above is equivalent to:

enum A = 1.2f;
enum B = 2.2f;
enum C = 3;
enum D = 4;

A named enum group I think has to have all the same type, because that  
enum is actually a new type, and all the values have to be of that type.
