/** @defgroup track_obj track_obj()
 * sigc::track_obj() tracks trackable objects, referenced from a functor.
 * It can be useful when you assign a C++11 lambda expression or a std::function<>
 * to a slot, or connect it to a signal, and the lambda expression or std::function<>
 * contains references to sigc::trackable derived objects.
 *
 * The functor returned by sigc::track_obj() is formally an adaptor, but it does
 * not alter the signature, return type or behaviour of the supplied functor.
 * Up to 7 objects can be tracked. operator()() can have up to 7 arguments.
 *
 * @par Example:
 * @code
 * struct bar : public sigc::trackable {};
 * sigc::signal<void> some_signal;
 * void foo(bar&);
 * {
 *   bar some_bar;
 *   some_signal.connect([&some_bar](){ foo(some_bar); });
 *     // NOT disconnected automatically when some_bar goes out of scope
 *   some_signal.connect(sigc::track_obj([&some_bar](){ foo(some_bar); }, some_bar);
 *     // disconnected automatically when some_bar goes out of scope
 * }
 * @endcode
