+static_assert(f == a);
----------------
Fun case

```
int constexpr f() {
    return [x = 10] {
       decltype(x) y; // type int b/c not odr use
                      // refers to original init-capture
       auto &z = x; // type const int & b/c odr use
                     // refers to lambdas copy of x
        y = 10; // Ok
        //z = 10; // Ill-formed
        return y;
    }();
}

constexpr int x = f();
```
