The normal way that I know is to insert a function like the following 
into Vector3f:

     string toString() {
         import std.string : format;
         return format("%s,%s,%s", x, y, z);
     }

Yeah, it doesn't make sense that a type of x, y, z should be a class. I 
would stay with a struct here.
