you should generally getMember on a variable

T t;
__traits(getMember, t, "name")

like that, that's as if you wrote t.name

It seems I can't use variable as member name:

    struct T {int a; string name;}
    T t;
    string s = "name";
    writeln(__traits(getMember, t, s));

Above code fails to compile. Any help?
