RAAI class for std::thread

class ThreadRAAI
{
public:
  typedef void (std::thread::*RAAIAction)(); // d-tor action

  ThreadRAAI(std::thread &&thread, RAAIAction a)
  : t(std::move(thread)), action(a) {}

  ~ThreadRAAI()
  { if (t.joinable()) (t.*action)(); } // need to do more protection for race cond

private:
  RAAIAction action;
  std::thread t;
};

ThreadRAAI t1(std::thread(doThisWork), &std::thread::join); // join on destruction

Note: Boost has an RAAI answer !!!

explicit operator bool() { ... }

- Function-template default arguments
- Delegation constructors
- Uniform initialization
- Non-static data member initializers (instead of c-tors)
- some_fun() = default;
  ... = delete; // restore suppressed default c-tor
- template "using" operators

  template <class T> using Vec = vector<T, MyAlloc<T>>;

  Vec<int> v;
  template <class T> void f(Vec<T> &);
  f(v);

- Variadic templates
