Re: (member) function returning pointer to functions like itself?

[Dima Volodin]

Well, I've ended up with

///////////////// cut /////////////////
#include <iostream>

class Fptr {
        class Fptr (*ptr) ();

public:
        Fptr (Fptr (*p) ()) : ptr (p) {}

        Fptr operator () () {
                return (*ptr) ();
        }
};

Fptr f1 ();
Fptr f2 ();

Fptr f1 () {
        cout << "f1" << endl;
        return f2;
}

Fptr f2 () {
        cout << "f2" << endl;
        return f1;
}

int
main () {
        Fptr f (f1);

        f = f ();
        f = f ();
        f = f ();
}
///////////////// cut /////////////////

but it's not exactly what I wanted - I get a pointer to a class here,
which is not as efficient as pointer to function. So the original
question still stands.

Cheers!
