Hello everybody.
I couldn't really think of a good title for this. It's just a little
question, about this example code:
http://pastie.org/private/4xqtze47dlx9fy9pn53sq
Apperantly I get a copy of Bar, when I call bar(), and it doesn't modify
the actual variable of the object. But if I define Bar as a class, it
works as expected (by silly me). Why is that? And if I want to use a
struct for this, is the passing around of a pointer (like in the
example) correct?

Structs are value types, so when you return one from a function or pass
as a function argument, it's actually a copy that gets handed around.
Classes are reference types, so when you move those around it's very
much like using a pointer. To get reference semantics on a struct, you
have either use it as a pointer or use the ref keyword to create a
reference.
