If you're stuck with plain C, something like defer would
be a huge relief over gotos as used in the Linux kernel.
Most C-code can be compiled with a C++ compiler, and
one can selectively use certain C++ features, such as
destructors.
I don't find the 'defer' proposal readable and I suspect it
may lead to more maintainability issues that simple gotos.
A new feature - or "advanced" macro (as distinct from a little function-like macro or a literal or constant value) - will always have maintainability issues as developers will be unfamiliar with it.
But a big potential benefit from a "defer" feature (or scope-guard template in C++) comes when replacing /complicated/ gotos, not simple ones.
