Simplified example: --- struct fooint { int i; auto opBinary(string op : "+")(int j) { return fooint(i + j); } @property fooint max() { return fooint(int.max); } } enum foolist { hi = fooint(0), bye } --- Produces the following error message: --- Error: no property `max` for type `fooint`, did you mean `onlineapp.fooint.max`? ---
