Hi,

I'd be interested in this approach, especially if it saves me some 
syntax. Can you give an example of the use of these classes (say, show 
us the implementation of scoped_ptr with it)? The problem I see is that 
I don't see a whole lot of typing getting saved with the standard 
full-ownership RAII classes. The other cases maybe.

Also, I'm not a Win32 programmer at all. Can you maybe explain in what 
sense these things can be copied but aren't shared? If two things have 
a copy, they are sharing the resource, no?

Thanks,
