/** @defgroup ptr_fun ptr_fun()
 * ptr_fun() is used to convert a pointer to a function to a functor.
 * If the function pointer is to an overloaded type, you must specify
 * the types using template arguments starting with the first argument.
 * It is not necessary to supply the return type.
 *
 * @par Example:
 *   @code
 *   void foo(int) {}
 *   sigc::slot<void, int> sl = sigc::ptr_fun(&foo);
 *   @endcode
 *
 * Use ptr_fun#() if there is an abiguity as to the number of arguments.
 *
 * @par Example:
 *   @code
 *   void foo(int) {}  // choose this one
 *   void foo(float) {}
 *   void foo(int, int) {}
 *   sigc::slot<void, long> sl = sigc::ptr_fun1<int>(&foo);
 *   @endcode
 *
 * ptr_fun() can also be used to convert a pointer to a static member
 * function to a functor, like so:
 *
 * @par Example:
 *   @code
 *   struct foo
 *   {
 *     static void bar(int) {}
 *   };
 *   sigc::slot<void, int> sl = sigc::ptr_fun(&foo::bar);
 *   @endcode
