iter_fold<Sequence, State, F>::type
Return type: Any type
            Semantics: Returns the result of applying
            iter_fold to a sequence of type
            Sequence, with an initial
            state of type State and
            binary function object or function pointer of type F.
          
            Linear, exactly result_of::size<Sequence>::valueF.
