I meant:

    int main(void)
    {
        int /* never changes */ a = 7;
        a = 5;
    }

But more to the point -- What I was getting at is that there are a lot
of core language features that can be achieved by using a 3rd party
code analysis tool.

I'm very surprised that 'structured binding' made it into the
language! I mean the following:

    auto& [a, b, c] = FuncReturnsTuple();

could simply be:

    auto tup = FuncReturnsTuple();
    auto &a = std::get<0u>(tup);
    auto &b = std::get<1u>(tup);
    auto &c = std::get<2u>(tup);

'Structured binding' is more of a disturbance to the core language
than the stuff I'm suggesting here.
