A C++ note in passing from an indie game developer. He notes that Boost has a similar feature already (see the BOOST_SCOPE_EXIT macros and discussion of alternatives) but likes that you can write the basic feature yourself in under 10 lines, have it work like a statement instead of a BEGIN/END macro pair, and use it with other C++11 features like lambdas.

I really like the scope(exit) statements in D. They allow you to keep the cleanup code next to the initialization code making it much easier to maintain and understand. I wish we had them in C++.

Turns out this can be implemented easily using some of the new C++ features...
