I think "defer" is coming [1], along with other goodies that simplified the life of C++ developers, but time will tell.

I really hope they approve the following:

    * auto
    * constexpr
    * lambda function
    * __typeof__ used as typeof; it behaves like decltype

It would lead to cleaner code without excessive macro magic; only where would be needed.
