In the context of C# this becomes a real pain. The isuee are arrays/lists. Because in C# an int[] array or List<int> is a reference. So even if you put a int[] in a struct this int[] will NOT be copied when you assign an instance of this struct to another instance: you will get a reference share which makes this annoying since you cannot do a proper deep copy with the language itself: you are forced to use reference copy instead of deep copy. In C++ this is easy because the types differentiate between pointer and non-pointer explicitly + you can overload the assignment operator.
