Actually the member can still be declared `private:` and the `obj.a.name` would not be portable. It appears GCC's implementation to make these members `public:` is conforming to c++11 but do not rely on this behavior. I've been told in ##C++ that the current C++14 draft says: `An init-capture behaves as if it declares and explicitly captures a variable of the form “auto init-capture ;” whose declarative region is the lambda-expression’s compound-statement` This change would make the named member access non-conforming
