At What point should you understand References?

I asked a question like this in an interview for a entry level programmer: var instance1 = new myObject{Value = "hello"} var instance2 = instance1; instance1.Value = "bye"; Console.WriteLine(instance1.Value); Console.WriteLine(instance2.Value); The applicant responded with "hello", "bye" as the output. Some of my co-workers said that "pointers" are not that important anymore or that this question is not a real judge of ability. Are they right?Read the article

What is the 'accumulator in HQ9+?
- by Koning Baard XIV
I was just reading a bit about the HQ9+ programming language ( http://esolangs.org/wiki/HQ9 , http://en.wikipedia.org/wiki/HQ9%2B and http://www.cliff.biffle.org/esoterica/hq9plus.html ), and it tells me something about a so called 'accumulator' which can be incremented, but not be accessed.
