Function returning pointer to itself?

Question

Is it possible in C++ to write a function that returns a pointer to itself?

If no, suggest some other solution to make the following syntax work:

som         


        

Answer 1

struct function
{
   function operator () ()
   { 
       //do stuff;
       return function();
   }
};

int main()
{
   function f;
   f()()()()()();
}

You can choose to return a reference to function if needed and return *this;

Update: Of course, it is syntactically impossible for a function of type T to return T* or T&

Update2:

Of course, if you want one to preserve your syntax... that is

some_type f()
{
}

Then here's an Idea

struct functor;
functor f();
struct functor
{
   functor operator()()
   {
      return f();
   }
};

functor f()
{  
    return functor();
}

int main()
{
    f()()()()();
}
