Andrew's comments on refcounting on DT objects notwithstanding --
I do like the _scoped() iterator quite a bit, FWIW. I think it's one 
of the better uses of the auto-cleanup and local variable declarations.

Direct uses of __free() are more questionable in my opinion.

Using advanced constructs to build clean subsystem APIs is great,
sprinkling unreadable constructs to save LoC is what C++ is for. 
(Lets see how many people this offends ;))
