Please note that even smart pointers (as in C++'s `std::unique_ptr`
etc.) do not guarantee memory safety. Yes, they help a lot writing
sound code (in particular exception-safe C++ code), but they do not
bring the same guarantees.

That's why using C language extensions (the existing ones, that is) to
recreate RAII/guards, smart pointers, etc. would only bring you to a
point closer to C++, but not to Rust.

Cheers,
Miguel
