/** @defgroup bind bind(), bind_return()
 * sigc::bind() alters an arbitrary functor by fixing arguments to certain values.
 * Up to 7 arguments can be bound at a time.
 * For single argument binding, overloads of sigc::bind() are provided that let you
 * specify the zero-based position of the argument to fix with the first template parameter.
 * (A value of @p -1 fixes the last argument so sigc::bind<-1>() gives the same result as sigc::bind().)
 * The types of the arguments can optionally be specified if not deduced.
 *
 * @par Examples:
 * @code
 * void foo(int, int, int);
 * // single argument binding ...
 * sigc::bind(&foo,1)(2,3);     //fixes the last (third) argument and calls foo(2,3,1)
 * sigc::bind<-1>(&foo,1)(2,3); //same as bind(&foo,1)(2,3) (calls foo(2,3,1))
 * sigc::bind<0>(&foo,1)(2,3);  //fixes the first argument and calls foo(1,2,3)
 * sigc::bind<1>(&foo,1)(2,3);  //fixes the second argument and calls foo(2,1,3)
 * sigc::bind<2>(&foo,1)(2,3);  //fixes the third argument and calls foo(2,3,1)
 * // multi argument binding ...
 * sigc::bind(&foo,1,2)(3);     //fixes the last two arguments and calls foo(3,1,2)
 * sigc::bind(&foo,1,2,3)();    //fixes all three arguments and calls foo(1,2,3)
 * @endcode
 *
 * The functor sigc::bind() returns can be passed into
 * sigc::signal::connect() directly.
 *
 * @par Example:
 * @code
 * sigc::signal<void> some_signal;
 * void foo(int);
 * some_signal.connect(sigc::bind(&foo,1));
 * @endcode
 *
 * sigc::bind_return() alters an arbitrary functor by
 * fixing its return value to a certain value.
 *
 * @par Example:
 * @code
 * void foo();
 * std::cout << sigc::bind_return(&foo, 5)(); // calls foo() and returns 5
 * @endcode
 *
 * You can bind references to functors by passing the objects through
 * the sigc::ref() helper function.
 *
 * @par Example:
 * @code
 * int some_int;
 * sigc::signal<void> some_signal;
 * void foo(int&);
 * some_signal.connect(sigc::bind(&foo,sigc::ref(some_int)));
 * @endcode
 *
 * If you bind an object of a sigc::trackable derived type to a functor
 * by reference, a slot assigned to the bind adaptor is cleared automatically
 * when the object goes out of scope.
 *
 * @par Example:
 * @code
 * struct bar : public sigc::trackable {} some_bar;
 * sigc::signal<void> some_signal;
 * void foo(bar&);
 * some_signal.connect(sigc::bind(&foo,sigc::ref(some_bar)));
 *   // disconnected automatically if some_bar goes out of scope
 * @endcode
 *
 * For a more powerful version of this functionality see the lambda
 * library adaptor sigc::group() which can bind, hide and reorder
 * arguments arbitrarily. Although sigc::group() is more flexible,
 * sigc::bind() provides a means of binding parameters when the total
 * number of parameters called is variable.
 *
 * @ingroup adaptors
