When we say "x + 1", we expect to get 100. x is > not some reference to 99, it is 99, just like Barrack Obama is not a > reference to the President of the United States, he is the POTUS. x is not the object 99. x is a variable that refers to an object that has the value 99. That python starts looking for that object and uses its value when your do arithmatics doesn't contradict that variables refer to objects. A reference is not pointer. When you use a reference parameter in Pascal, it behave like an ordinary parameter within the procedure block, you don't have to treat it like a pointer.
