auto obj = [ name = 1, a = [name = 1]{} ]{}; obj.a.name;

test.cc: In function ‘int main()’: test.cc:5:38: warning: already captured ‘name’ in lambda expression auto obj = [ name = 1, a = [name = 1]{} ]{}; ^ test.cc:7:9: error: ‘struct main()::<lambda()>’ has no member named ‘name’ obj.a.name;

Why would you ever do:

  [x=1, y="foo"]{
    // use x, y
  }();

  auto x = 1;
  auto y = "foo";
  // use x, y

?
