you can actually do it with your own code. behold:

struct A{
//int a; // comment this line
int _a; // make the actual var renamed...

// then add a ref property with template file/line params
@property ref int a(string file = __FILE__, size_t line = 
__LINE__)() {
         pragma(msg, file); // and print those out
         pragma(msg, line);
         return _a;
}
  void fun(){
   a++; // HERE
   alias b=a;
  b++; // HERE
  }
}

void fun(){
  int a; // NOT HERE
  A b;
  b.a ++ ; // HERE
}



Can be a bit trickier in other cases but there's a compile time 
list of uses.
