/**
 * @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 a
 * runtime error in checked mode.
 * @description Checks that passing in a double factor on a Point<int> causes a
 * runtime error in checked mode.
 * Checks that passing in an int factor on a Point<double> does not causes a
 * runtime error.
