// Bind() is an overloaded function that converts method calls into function
// objects (aka functors). The method object is captured as a scoped_refptr<> if
// possible, and as a raw pointer otherwise. Any arguments to the method are
// captured by value. The return value of Bind is a stateful, nullary function
// object. Care should be taken about the lifetime of objects captured by
// Bind(); the returned functor knows nothing about the lifetime of a non
// ref-counted method object or any arguments passed by pointer, and calling the
// functor with a destroyed object will surely do bad things.
//
// Example usage:
//   struct Foo {
//     int Test1() { return 42; }
//     int Test2() const { return 52; }
//     int Test3(int x) { return x*x; }
//     float Test4(int x, float y) { return x + y; }
//   };
//
//   int main() {
//     Foo foo;
//     cout << rtc::Bind(&Foo::Test1, &foo)() << endl;
//     cout << rtc::Bind(&Foo::Test2, &foo)() << endl;
//     cout << rtc::Bind(&Foo::Test3, &foo, 3)() << endl;
//     cout << rtc::Bind(&Foo::Test4, &foo, 7, 8.5f)() << endl;
//   }
//
// Example usage of ref counted objects:
//   struct Bar {
//     int AddRef();
//     int Release();
//
//     void Test() {}
//     void BindThis() {
//       // The functor passed to AsyncInvoke() will keep this object alive.
//       invoker.AsyncInvoke(rtc::Bind(&Bar::Test, this));
//     }
//   };
//
//   int main() {
//     rtc::scoped_refptr<Bar> bar = new rtc::RefCountedObject<Bar>();
//     auto functor = rtc::Bind(&Bar::Test, bar);
//     bar = nullptr;
//     // The functor stores an internal scoped_refptr<Bar>, so this is safe.
//     functor();
//   }
