vote += MAX_INT for the above suggestion which btw is also the 
solution in Java 5.0 which provides an EnumSet type. At the 
moment eums are completely broken in D and IMO they are even 
worse that the unsafe C counterparts. C# is a lousy example here 
since its design is only very slightly better than the original C 
semantics.

I suggest looking into the Java implementation of Enum and 
EnumSet types which provides both type safety and convenience.
