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);
}

I haven't used hashOf before, though assuming no  equal values, 
which I generally wouldn't do, I take it this is reliable? I 
haven't tried it before, and I dont know how to effectively 
compare it to using 'switch(w.to!string)' & 'case 
Wind.B.stringof' (regarding speed/reliability).
