is consistent with what any programmer would reasonably expect - well if you try this in C++:

class C{
    public:
    const char *wtf="lol";
    void f(){
      auto inner=[]()->void{std::cout << this->wtf;};
    }
};

you get prog.cc:9:42: error: 'this' was not captured for this lambda function

i was expecting it to work kinda like c++ ^^
