AFAIK, native mode is default if compiler supports typeof/decltype. So you can 
skip type registration if your compiler supports typeof natively.

Have you tried boost.lambda? I bet you will feel comfortable with ScopeExit 
syntax after writing 10 ScopeExit bodies but mastering lambda skills would take 
a month.
I spent 5 minutes writing and debugging lambda for Alternatives.ScopeGuard 
section but it took me only 10 seconds to type ScopeExit.
