Besides the problem with equal values, what's wrong with that:

alias Thing = Tuple!(int, int);
enum Wind {
     A = Thing(0, 1),
     B = Thing(0, 2),
     C = Thing(0, 2)
}

void some_function(Wind w) {
     switch (w.hashOf) {
     case Wind.B.hashOf:
         break;

     default:
         assert(0);
     }
}

void main() {
     some_function(Wind.B);
     writefln("%d%d", Wind.C.expand);
}
