function.
It's hardcoded in the compiler. If you've got the Rotor sources
installed, the check is done in TYPESYM::isSpecialByRefType().

Hmmm. I really wonder why they didn't simply add an attribute to
It gets worse. Look at the following code:
using System;
class Class1
{
static void Main(string[] args)
{
ArgIterator iter = new ArgIterator(Foo(__arglist(1, 2, 3)));
}
static RuntimeArgumentHandle Foo(__arglist)
{
return __arglist;
}
}
This is effectively the same as
Hi!
Look at the code below:
using System;
namespace IteratorTest
{
public class Test
{
public object Method()
{
ArgIterator iterator;
return iterator;
}
}
}
When I try to compile it I get :

Hm, ArgIterator is a struct, so it would have to be boxed to be

Ok, so take a look at this:
using System;
namespace IteratorTest
{
public struct MyStruct
{
}
public class TestClass
{
public Object MethodOne()
ArgIterator is a special type. It contains a pointer to the stack, so it
isn't allowed to escape the current method. Otherwise, you'd have a
pointer pointing into the middle of nowhere.

Documentation for this anywhere?
Especially on HOW they stop the boxing to happen.

OK, I understand now, but where did you find out about this?
I think it is documented somewhere in the ECMA CLI specification. I'm
not sure, it's been a while. BTW, there is another type that also
behaves like this: System.TypedReference.

I would guess that it has not so much to do with ArgIterator being a
