Showing the compiler error message would have been helpful. I suspect
you'll have seen some type error, since you didn't make f2 a static
function.

Here, f2 is a normal (non-static) member function, meaning it should be
called _on_ an object (under water it actually has an extra "this"
argument).

I think declaring f2 as a static member function would fix you problem.
If you need f2 to remain a normal function, you'll have to create a
list that stores both the member function to call, as well as the object
to call it on.  Google for "member function pointer" for more info.
