I can't also have variables like 'int i', it throws access violation. But why in the DMD page here http://www.digitalmars.com/d/class.html is listed a bunch of classes with 1 to 3 non-static members like int i?

Man, C# is a lot more flexible in this topic, why can we have non-static members in C# and not in D?
