What C++ really needs is an automated way to handle exceptions in destructors, similar to how Java does in its try-with-resources finally blocks.

While not automated, you can make use of function-try-blocks, e.g.:

    struct Example {
        Example() = default;

        ~Example()
        try {
        // elease resources for this instance
        } catch (...) {
            // take care of what went wrong in the whole destructor call chain
        }
    };

Now with C++26 reflection, one could eventually generate such boilerplate.
