Thanks, I did safety critical embedded development for while, in C++. We did turn off a bunch of features of course. We never heap-alloced for example. But destructors were used extensively to make sure that important actions happened during error conditions. We were lucky to be able to use C++ because we had a compiler for our target platform. Not every target has a C++ compiler, so I think adding something as useful as scope-bound cleanup to C makes perfect sense.
