S has 3 different properties, x, y, z:

int x;
int y() { return 1;}

int z(S s) { return 1;}
pragma(msg, typeof(S.init.x).stringof); // int
pragma(msg, typeof(S.init.y).stringof); // int()
pragma(msg, typeof(S.init.z).stringof); // int
Is there a trait I can call/use to consistently get "int" from
all 3?
