typenamed iterator is not a type

I'm writing a templated class, which involves use of iterators. I've found the many questions about how you need to typename an iterator if you're using it with a template, so I'm wondering why it's still not working.

#pragma once

#include <iterator>
#include <list>
#include <tuple>

template <class T>
class Quack
{
    private:
        std::list<T> data;
        typename std::list<T>::iterator iter;

    public:
        Quack();

        void insert(T dat);
        std::tuple<T, T> poppop();

    private:
        //error: 'iter' does not name a type
        iter binarySearch(T toFind, std::list<T>::iterator min, std::list<T>::iterator max);
};

I also tried typedef typename std::list<T>::iterator iter;, but that throws up the error "std::list::iterator is not a type"

So given that I'm using typename, what is it that I'm doing wrong?

I'm using g++ 4.4.5 with the argument -std=c++0x, if it's relevant.
