struct S2 { void f(int i); };
void S2::f(int i)
{
    [=]{};        // OK: by-copy capture default
    [=, &i]{};    // OK: by-copy capture, except i is captured by reference
    [=, *this]{}; // until C++17: Error: invalid syntax
                  // since C++17: OK: captures the enclosing S2 by copy
    [=, this] {}; // until C++20: Error: this when = is the default
                  // since C++20: OK, same as [=]
