The following example is not supported by the proposed resolution and remains ill-formed:

  int main() {
    int x = 0;
    auto lambda = [x] (this auto self) { return x; };
    using Lambda = decltype(lambda);
    struct D : private Lambda {
      D(Lambda l) : Lambda(l) {}
      using Lambda::operator();
      friend Lambda;
    } d(lambda);
    d();
  }
