I think G++ and Clang support computed gotos in C++, that has RAII.

Generally when you use computed gotos, you are writing low level special code,
so the programmer should be trusted. So some unsafety is acceptable when you
use computed gotos.

I asked for computed gotos in D, and failing that I have asked for something
less, to avoid the un-portability, I didn't even receive an answer from Walter:
