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)

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

string[] staticMembers(T)() {
    string[] statics;

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

    return statics;
}

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