The article is a bit dense, but what it's announcing is effectively golang's `defer` (with extra braces) or a limited form of C++'s RAII (with much less boilerplate).
Both RAII and `defer` have proven to be highly useful in real-world code. This seems like a good addition to the C language that I hope makes it into the standard.
