alt Hacker NewsA long overdue feature.
Though I do wonder what the chances are that the C subset of C++ will ever add this feature. I use my own homespun "scope exit" which runs a lambda in a destructor quite a bit, but every time I use it I wish I could just "defer" instead.

Various macro tricks have existed for a long time but nobody has been able to wrap the return statement yet. The lack of RAII-style automatic cleanups was one of the root causes for the legendary goto fail;[1] bug.

Just hope those lambdas aren't throwing exceptions ;)

In many cases that's preferred as you want the ability to cancel the deferred lambda.
Never, you can already do this with RAII, and naturally it would be yet another thing to complain about C++ adding features.
Then again, if someone is willing to push it through WG21 no matter what, maybe.
