digitalmars.D.learn - how do I get only static member of a class?

I found no way with __traits() on std.traits. I found 
isStaticFunction and isStaticArray but nothing about a member. Is 
this by desgin?

Give a class like:


 class C { static int a, b, c; int d; }


I'd like to get a, b and c.

I'm using this:

 __traits(allMembers, C)

string[] staticMembers(T)() {

     foreach (m; __traits(derivedMembers, T)) {
         import std.traits : hasStaticMember;
         static if (hasStaticMember!(T, m)) {
             statics ~= m;
         }
     }

     return statics;
}

void main() {
     pragma(msg, staticMembers!C);
}
