Example

struct A
{
    ~A() noexcept(false) try
    {
        // destructor body 
    }
    catch (...)
    {
        // exceptions of destructor body are caught here
        // if no exception is thrown here
        // then the caught exception is re-thrown.
    }
};

Note that, although this is possible, one needs to be very careful with throwing from destructor, as if a destructor called during stack unwinding throws an exception, std::terminate is called.
