| * @assertion Point<T> operator *(num factor) |
| * This function accepts a num as its argument only so that you can scale |
| * Point<double> objects by an int factor. |
| * Because the star operator always returns the same type of Point that |
| * originally called it, passing in a double factor on a Point<int> causes causes a |
| * compile time error |
| * @description Checks that passing in a double factor on a Point<int> causes a |
| * runtime error |
| * Checks that passing in an int factor on a Point<double> does not causes a |
| * runtime error. |
