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.

I don't know if it is like in Go, but there is a defer suggestion: http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2589.pdf
