But what if the function and the functor creation is in the same class . I
thought member function of the same class where functor creation is done will
not require TypedMethod functor creation because we dont need an object to call
a function in the same class. It should be same as when the function doesnt
belong to any class where also we dont need any object .
In the traverse sample , the function for the TypeMethod functor is in a
different class.
Have I understood it wrong ?
